Hello,
In my past posting for tty(1) I inadvertently allowed a bug to get
past me. Here are the diffs to fix ttyname(3). The ttyname(3) I posted
will work only because of the way U**X and MINIX set up their directory
structure and where they place their devices. This fix will check if
the devices are also the same and keep ttyname() honest.

Hello,
This is a little utility that I wrote when I first started to use
MINIX. It behaves just like tty(1) for UNIX. In writing it I also
needed to write ttyname(3) library call. I hope both the tty(1) and
ttyname(3) is usefile. Just follow the instructions in the "INSTALL"
file and enjoy.

Hello,
Here I am again. This time I have the directory(3) library calls.
I have followed the BSD description as closely as the BSD 4.3 PRM allows
me to (some entries have so little info in them). I hope they can be
of some use.
N O T E
-------
I would not suggest using these routines if you already have a tried
and tested set of directory functions that work for you. Use these as a
last resort (I have such confidence in my code). I know the readdir(),
opendir(), and closedir() work properly. Although, I had to make some
assumptions on how to implement telldir() and seekdir(). I basicly decided
to pass and returned what was needed for the lseek() call. I hope this
was correct. If anyone knows the correct specs on these calls or know
where to point me to please do. Enjoy.

XInstallation instructions:
X-------------------------
X
X1. install dir.h in /usr/include/sys.
X
X2. Add "typedef unshort ino_t" or "#define ino_t inode_nr" to
X /usr/include/sys/types.h depending on your thinking how this

X3. Compile dir.c as a library routine and place in /usr/lib/libc.a.
X If you are using the makelibc shell script that was posted quite
X awhile back just append "ar av libc.a dir.s" to the beginning and run.
X I am including my version if you don't have it.
X
X4. Run makefile to compile tst.c and run it to test directory(3).
X
X5. Enjoy
X
XNotes:
X-----
X
X I'm not sure on the exact operations performed by telldir() and
Xseekdir(). I set up telldir() to return the current position (long int
Xlike seek()) within the opened directory. Seekdir() was set up likewise,
Xit will set the file postion within the opened directory without regard
Xif it entry boundries or if the entry is active (d_ino entry is non-zero).
X
X In all actuality, I would suggest that if you use the POSIX version of
Xdirectory(3) that came across the net lately. At the time I wrote these
Xroutines I was attempting to get the BSD version of arc to work under MINIX.
XI am now leaning towards using the POSIX implementation. I am including
Xthese only for the sake of completeness for my scandir(3) routines I'm also
Xposting.
X
X I must also state I don't garentee that theses routines work correctly.
XI have tested them and found them to work as I need them to. I would
Xsuggest you run them through your own tests to decide if they work for
Xyour own purposes. (Gee - I have such confidence in my own code :-)

Is there well, i'm glad i'm not the only one having this problem. i've been trying to track this problem down for months. maybe we can team up. here's what i know of the problem. in tty_task, the message structure tty_mess is declared so that it is allocated on the stack. the problem seems to be that some routine corrupts 6 or 8 bytes just below the address of the structure. this of course usually contains the reuturn address and stuff from the receive() call tty_task makes. i know the corruption is relative to the structure address becuse i can make other declarations in tty_task to move the location of the structure. the problem can be "solved" by allocating a char array just below the structure, although memory in the array still get corrupted. i do not care for this solution. -- Bing H.

Reply-to: INFO-MINIX@UDEL.edu
Comments: To: info-minix@UDEL.EDU
Enclosed is my implementation of PS for minix. Please excuse the
strange coding style. PS expects a native minix maintence enviornment(
minix c compiler, asld, ...). For a cross compiler based minix it
will require some changes. This version of PS is based on the V7
documentation with some slight changes in the output
for minix.

I have incorporated various fixes from the network into the shell. Here
are diff files that you can apply to the V1.2 shell sources to generate the
revised shell sources. When you are done, you should get something like this:
-rw-r--r-- 1 ast 7321 Dec 19 16:46 sh.h
-rw-r--r-- 1 ast 14508 Dec 19 16:46 sh1.c

-rw-r--r-- 1 ast 9219 Dec 19 16:49 sh5.c
-rw-r--r-- 1 ast 92 Dec 19 16:50 sh6.c
Please post any new bug reports to the net.

Check to see that this file has the same size and sum as elle.uuencoded. The file ellec should be checked against ellec.uuencoded. Finally .ellepro.b1.uu should also be checked. If all three are ok, uudecode them and compare to elle, ellec, and .ellepro.b1, respectively. The announcement is not encoded, nor is the shar file, which contains defprf.e, .ellepro.e, and help.dat. Installation instructions are at the end of the announcement. I have tested ELLE fairly extensively on a Z-248 AT clone and found no errors. If you find errors, please post them to this group. I will try to answer questions, etc. as best I can. It is conceivable that our network link will die shortly, because we have intelligent I/O boards installed and they know that the university is closed for vacation until January 4, 1988, so that if they break, nobody will touch them for two weeks and they can have a nice rest. If I am suddenly silent, it is more likely due to this than to my hiding from all the abuse about to be aimed at me because ELLE is not full Emacs. Finally, now that I have your undivided attention, how about somebody taking a good look at the sed I posted before, with an eye to getting the last bugs out of it. If that occurs, we can change the MINIX shar to use sed, and thus be compatible with the UNIX shar. To test sed, make a sed script that converts like this: /and/s//QQQ1/ /the/s//QQQ2/ /has/s//QQQ3/ /this/s//QQQ4/ etc. Then run this on a large piece of text. Then convert it back with another sed script and compare the output with the original. Put some long lines in because it seems to stumble on these. Andy Tanenbaum (ast@cs.vu.nl)

NAME
ps - process status
SYNOPSIS
ps [-alx ]
DESCRIPTION
PS prints information about active processes. It does so by
examining kernel, mm, and fs address spaces. The 'a' option
asks for information about all processes with terminals
(normally only ones own processes are displayed); 'x' displays
processes even without terminals; 'l' asks for the long listing.
The normal short listing contains the PID, TTY, TIME, and the CMD.
The long listing contains:
F - 01: in use; 02: waiting; 04: hanging; 10: paused;
20: alarm on; 40: seperate I & D spaces.
S - s - suspended, r - running (process FS status)
UID - owners uid
PID - process id
PPID - parents process id
ADDR - core address(in hex)
SZ - size of code+data+stack(in hex)
WCHAN - the pid or name of the process its waiting on
TTY - owning tty
TIME - system & user time in seconds for the process
CMD - command name of process
FILES
/dev/mem core memory
/etc/maint.info kernel, fs, and mm maintence info
PORTABILITY
Heavily dependent on the basic structure of minix on 8088.

ELLE FOR MINIX
Andy Tanenbaum (ast@cs.vu.nl)
1. INTRODUCTION
I have good news for the Emacs fans among the MINIX users. I have
ported an Emacs clone to MINIX. The clone is called ELLE (ELLE Looks
Like Emacs). It was written by Ken Harrenstien of SRI. His e-mail
address is klh@sri-nic.arpa. ELLE is not full Emacs (surely you didn't
expect that?), but it has about 80 commands and is highly usable. I am
not distributing the (700K) source, but you can get it from Vincent Broman's
MINIX archive. Instructions will be posted shortly.
For people who don't know about Emacs, it is a VERY VERY big editor
that can do anything you can imagine, if you have enough patience to wait
forever. Mined was inspired by Emacs, and has the same style, but only a
small subset, and is much faster. Compared to mined, ELLE has the following
advantages:
1. It can edit files as large as the disk can hold (vs. mined, 38K)
2. It can handle multiple windows (2, to be specific)
3. You can have lots of files in the editor simultaneously
4. You can change the key bindings relatively easily
5. It has a bunch of additional commands that mined is missing
Compared to Emacs, it has the following advantages:
1. It is much, much smaller
2. It is a lot faster
3. It has #ifs for a large number of machines
The disadvantage of ELLE compared to mined is that regular expressions are
missing, and compared to Emacs that hundreds and hundreds of commands are
missing.
For the record, I am aware of Jove and Scame and have tried both.
Without getting into all the details, ELLE seems much better suited to
MINIX. It is very fast, for example. Implementing full Emacs on MINIX
is unthinkable.
One problem is that I have been unable to compile ELLE on MINIX.
I can compile all the files, but asld runs out of space when linking
everything. I have made a preliminary attempt to see if asld can be
sfixed, but it really appears to be out of space. The only solution is
to remove a few of the ELLE source files (such as internal diagnostics
and paragraph filling). I haven't really worked on this and definitely
don't have the time now. My hope is that one or more of you will do that.
I cross compiled ELLE on PC-IX. That works fine. People who are using
Turbo C might try that.
1.1 Key bindings
Mined only has a small number of commands. All of them are either of
the form CTRL-x or are on the numeric keypad. Emacs, in contrast, has so
many commands, that not only are all the CTRL-x commands used up, but so
are all the ESC x (escape followed by x; escape is not a shift character,
like CTRL). Even this is not enough, so CTRL-X is used as a prefix for
additional commands. Thus CTRL-X CTRL-L is a command, and so is CTRL-X K.
Fortunately, it wasn't necessary to distinguish upper case from lower case,
so what is conventionally written as CTRL-X K really means CTRL-X k.
The result of all this is that many commands need three or four key
strokes to execute. The command "CTRL-X (" requires you to touch CTRL, X,
shift, and (, for example, because the parentheses are upper case.
A lot of people think 4 (usually pretty obscure) key strokes is too much work.
For this reason, Emacs and ELLE allow users to assign their own key bindings.
In ELLE this is done with "user profiles." A user profile is a file listing
which function is invoked by which key stroke. The user profile is then
compiled by a program called ellec into binary form. When ELLE starts up
it checks to see if a file .ellepro.b1 exists in $HOME. If it does, this
file is read in and overrides the default bindings. It is also possible to
tell ELLE to read in a specific file as profile.
I have written a user profile that simulates the mined commands fairly
well (but not perfectly, since there are a few things that ELLE
simply cannot perform). This profile also includes the other ELLE functions,
mostly in the form ESC x, rather than the 3 and 4 key stroke Emacs commands.
In addition, the numeric keypad is used, and lowercase characters were used
in preference to uppercase where possible (e.g., = instead of +).
Furthermore, I have made an attempt to choose mnemonic names for most
commands, although the goals of choosing mmenomic names and having all the
common command be no longer than two lowercase key strokes are in conflict.
If you have never used Emacs, I suggest that you use the mined profile.
It should be easy to learn, since it is a superset of mined. If you already
know Emacs, you have a choice of familiarity vs. fewer key strokes. In
particular, I have avoided the many CTRL-X y and CTRL-X CTRL-Y sequences
that Emacs has. A third option is to build your own profile using ellec.
The keybindings are described below.
ELLE has a character-oriented view of the world, not a line oriented
view, like ed. It does not have magic characters for searching, however, you
can use line feed in search patterns. For example, to find a line consisting
of the three characters "foo" all by themselves on a line, using the mined
bindings (see below), use the pattern: CTRL-\ CTRL-J f o o CTRL-\ CTRL-J.
The CTRL-\ means to interpret the next character literally, in this case it
is CTRL-J, which is line feed. You can also search for patterns involving
multiple lines. For example, to find a line ending in an "x" followed by a
line beginning with a "y", use as pattern: x CTRL-\ CTRL-J y.
2. MINED KEY BINDINGS
These are the key bindings if the binary user profile, .ellepro.b1,
is installed in $HOME. The ESCAPE key followed by a number followed by a
command causes that command to be executed "number" times. This applies
both to control characters and insertable characters. CTRL-X refers to a
"control character." ESC x refers to an escape character followed by x.
^X Y refers to CTRL-X followed by y. To abort the current command and go
back to the main loop of the editor, type CTRL-G, rather than CTRL-\.
Only a few commands are of the form CTRL-X Y. All of these are also
bound to CTRL-X CTRL-Y, so you can hold down CTRL and then hit X Y, or
release control after the X, as you prefer.
The key bindings that are not listed should not be used. Some of them
actually do things. For example, the ANSI escape codes ESC [ x are bound
to ^X Y for a variety of y.
Some commands work on regions. A region is defined as the text between
the most recently set mark and the cursor.

ESC L Set entire region between mark and cursor to lower case
MISCELLANEOUS
ESC F Find file and read it into its own buffer
ESC Z Incremental search
ESC Q Like CTRL-R, but queries at each occurrence (type ? for options)
ESC R Reset the user profile from a file
ESC H Help (ELLE prompts for the 1 or 2 character command to describe)
ESC ; Insert a comment in a C program (generates /* */ for you)
^X X Exit the editor (same as ESC X and CTRL-X CTRL-X)
The major differences between ELLE with the mined profile and mined are:
1. The definition of a "word" is different for forward and backward word
2. The mark is set with CTRL-^ instead of CTRL-@
3. Use CTRL-G to abort a command instead of CTRL-\
4. Use CTRL-\ to literally insert the next character, instead of ALT
5. CTRL-E adjusts the window to put the cursor in the middle of it
6. To get and insert a file, use ESC G instead of CTRL-G
7. To go to line n, type ESC n CTRL-[ instead of CTRL-[ n
8. You exit with CTRL-X CTRL-X and then answer the question with "y".
9. There are many new commands, windows, larger files, etc.
Needless to say, if it had been easy to eliminate these differences and
have the two editors be fully compatible, I would have done so. In each
case it would have been a significant undertaking.
3. EMACS KEY BINDINGS
This section was adapted from the official ELLE documentation.
CURSOR MOVEMENT
CTRL-F Forward one character.
CTRL-B Backward one character.
CTRL-H Same as CTRL-B: move backward one character.

During an incremental search, the following characters
have special effects:
"normal" chars - Begin searching immediately.
^G - Cancel I-search, return to start.
DEL - Erase last char, return to last match.
^S, ^R - Repeat search (or change direction).

ESC % Query Replace. Asks for a search string, then
for the replacement string, and begins searching.
Stops at each match and waits for a command.
Type "?" to see your options.
CTRL-X % Replace String. Like Query Replace, but simply
replaces all matches, without stopping to ask.
MARKING AREAS
CTRL-^ Set mark
CTRL-X CTRL-X Exchange cursor and mark.
ESC H Mark Paragraph. Sets mark and cursor to surround a para.
CTRL-W Wipe-out -- kills a "region":

4. INSTALLING ELLE ON MINIX
I have distributed the following files:
elle (executable binary of the editor)
ellec (executable binary of the profile compiler)
.ellepro.e (mined profile in source form)
.ellepro.b1 (mined profile in binary form)
defprf.e (default profile in source form)
help.dat (help file)
Before starting to install ELLE, be sure you have updated to the tty.c
that supports both ANSI input and output. Also install the /etc/termcap
file that goes with this tty driver.
HOW TO INSTALL ELLE
Step 1:
Install 'elle' and 'ellec' in your /bin or /usr/bin directory.
Step 2:
Install help.dat in /usr/src/elle/help.dat
Step 3:
If you want to use the mined-like commands, install .ellepro.b1 in $HOME
Step 4:
Type 'elle filename' and you are up and running.
HOW TO CREATE YOUR OWN USER PROFILE
Step 1:
Modify .ellepro.e to suit your taste
Step 2:
Install .ellepro.e in $HOME
Step 3:
Type: ellec -Profile
Step 4:
Check to see if $HOME/.ellepro.b1 was created
If you have questions that are likely to be of interest to other people,

I can't recall if it has made it to MINIX-L on Bitnet, but I do know that it is on the archive server for Bitnet on the LISTSERV at NDSUVM1 (I maintain this). Other networks can access this mail, but it works best for people on BitNet due to the 80-column restriction on mail. > I would rather not uuencode >if I don't have to since that will increase the volume by tens of kilobytes. >What does BITNET actual do? If it just mungs tabs or something simple, I >can replace all the tabs with ! or ? or some other character that is not >otherwise used. BitNet has always been a problem. First of all, they run an IBM protocol which limits lines to 80 characters. To get around this, IBM has come up with TWO "packetising" techniques ("DISK DUMP and "NETDATA" to those unfortunate enough to know) which combine short lines and break up long ones. Unfortunately, mail does not use either of these techniques, so lines over 80 characters long either get truncated or wrapped (depending on what software you're using and how it is feeling today). I feel that the BitNet people should come up with some solution of their own to make themselves compatable with the rest of the world, rather than the rest of the world changing to accomodate the IBM world. There is no reason that all other networks should suffer the increased load of uuencoded sources or manually translated characters just because of brain dammage on BitNet. For a long time we at NDSU recieved all of our news over BitNet, and I worked around the problem of wrapped lines and expanded tabs (translation tables were no problem, fortunately). So what comes across BitNet *IS* useable; it just takes some work, and a few different techniques. Of the problems I ran into, the biggest was tab expansion. I worked around this problem with patches by using "patch" with the "loose" option (-l). Wrapped lines showed up on the filenames of the shar archives and on a few comments (a linefeed between * and / on a terminating comment). These are readily visible in sources that use 'sed' and start all lines with a 'X', but had to be manually fixed. Translation tables have not plagued me with Minix sources, but it still exists. The problem comes from the lack of a standard EBCDIC to ASCII translation, as well as internal inconsitiencies in EBCDIC. Curly braces ( { } ) are a classic one (There are two sets of them; one for IBM's "TN" print train and another for the "PN" train. IBM terminals NORMALLY use the "PN" ones, but many Unix systems use the "TN" one. And a major mail gateway to BitNet is a Unix machine). Tabs are an even worse situation. IBM's editors do not use tab characters, but instead display them as a strange character or something (depending on how you connect to your IBM). As a result, the gateways expand tabs. Most gateways will expand tabs on a FOUR character boundary rather than 8. So, in short, the problems with BitNet can be worked around by the people on that network so rest of us don't have to suffer for it. Or would you prefer to go back to using punched cards? >Andy Tanenbaum (ast@cs.vu.nl) -- Glen Overby Bitnet: ncoverby@ndsuvax UUCP: uunet!ndsuvax!ncoverby

X;;; ELLE Default Command Profile - "defprf.e"
X;;;
X;;; This file is input to the ellec program. It defines the default
X;;; command key bindings that ELLE uses, in the absence of an individual
X;;; user profile.
X;;; These defaults attempt to emulate the default EMACS command key
X;;; bindings. Differences, where known, are commented.
X;;;
X;;; "ELLE" means the function is unique to ELLE.
X;;; E/G: (cmd altnam) "thisname";
X;;; "E:" refers to TOPS-20 EMACS, "G:" refers to Gnu Emacs.
X;;; (cmd) This function exists but is bound to "cmd" instead.
X;;; (*) function exists but is not bound to any specific key.
X;;; () function does not exist.
X;;; (=) function exists, with same binding (normally omitted)
X;;; altnam Name by which this function is known.
X;;; "thisname" - name of function bound to this command.
X;;; - means the command is unbound (undefined).

I am working on it (model 60) and have a three person mailing list of others who are interested. I will add you to it. So far, I have MINIX up and running with floppy only. I have rewritten the floppy driver to use BIOS calls, so the system waits while the floppy is being serviced. However, later AT and all PS/2 BIOSes have hooks to deal with this, so these will eventually be put in. I just redid the hard disk driver last night, but for some reason the system hangs whenever a read is attempted. I'll be looking into this over the next few days. Although the fixes are in no really distributable form right now, if you or anyone needs them now, I can send you some quick fixes to at least get you running. I probably will post the BIOS drivers when I get everything running, and then again when the busy-wait hooks have been put in. alan

Comments: To: info-minix@UDEL.EDU
For those of you who want to fetch the ELLE sources and work on them, be
warned that the MINIX make program can't handle the way Ken did things.
In particular, when you invoke make, the makefile makes another makefile
that is then executed. The MINIX make first parses the entire makefile,
and dies because it encounters macros that will only be defined when the
other makefile is executed. Since the semantics of makefiles are defined
nowhere, it is hard to tell if this is a bug, a feature or what. In any
case, I just made up my own little makefile for use on PC-IX. Here it is.

Hello -
Some time ago I tried booting MINIX 1.1 on a Tandy Model 4000.. and
saw the boot message pop up. Unfortunately, the hardware was not set
to MINIX requirements and I could not continue the load. However, after
having tried 1.1 on about 10 different machines, I was reasonably
confident that it would run on a 4000.
Has anyone tried MINIX 1.[12?] on other '386-based AT-style
hardware?
Please respond with e-mail direct.. if enough queries/requests,
I'll summarize and post to the group.
Regards,
Mark Becker

Version 1.2 of MINIX in 256K & 640K PC, 512K AT, >mag tape, and the IBM slipcase version with the abridged book are all >in stock. > >Andy Tanenbaum (ast@cs.vu.nl) After having waited one month for delivery, I finally received the Minix version 1.1 (!) disks for the IBM-PC 640k system. I immediately called Prentice-Hall and spoke to a man by the name of Jim Fagan who told me that the disks for version 1.2 would *not* be available for shipment until February 1988. He also told me that the changes in version 1.2 were relevant only to the IBM-AT version hard disk support, and, hence, were of no consequence to the IBM-PC disks that I ordered. It was my understanding that the source code for IBM-AT specific device drivers are included with the IBM-PC disk set, and I would expect the IBM-PC disks to contain any revisions pertaining to the IBM-AT. Since I intend to run Minix on both systems, I require working drivers for both the PC and AT. It would seem that there is still some confusion and/or misinformation surrounding the distribution of the Minix software. Does anybody *really* know what is happening here? I am sure that all Minix enthusiasts agree that Dr. Tanenbaum's brilliant contribution deserves better handling and support. In the meantime, could someone please direct me to a convenient source for the version 1.2 diffs. I have abandoned hope of ever getting them from P-H. -- Bob Best uucp: ...{trwrb,hplabs}!felix!dhw68k!bob InterNet: bob@dhw68k.cts.com

There were a lot of changes that people suggested for 1.3b, so here comes 1.3c. If nobody complains within a week or so, I'll send it off to Prentice-Hall and that will be the end of 1.3. The cdiffs that follow are all relative to 1.3b. After upgrading from 1.3b to 1.3c, please keep the full set of 1.3c files on diskette, so we can use that as a base for diffs during the coming year. I do not plan to do 1.4 until I have rewritten my architecture book, something that may take a year. I will discuss plans for 1.4 later. If you are completely lost with 1.1 -> 1.2 -> 1.3a -> 1.3b -> 1.3c now, I will make an upgrade kit that P-H will sell starting around Dec. That will simply be all the 1.3c sources plus the 1.2 compiler binaries and elle. The 1.3 compiler is identical to the 1.2 compiler. For those of you who tuned in late, there is a Pascal compiler as well, available from UniPress and Transmediair (see the preface of the book for their addresses). Please don't call P-H about the upgrade kit until around Dec. They will be all confused. The kernel has been modified quite a bit. I split tty.c into 5 files: tty.h, ttymaps.h, tty.c, console.c, and rs232.c. Mostly because I thought the latter was such a cute name. I saw the new tty.c from Down Under, but I prefer to stick with mine. At least I understand that one (sort of). Changes and improvements to it are welcome, but I am not going to throw it away. One improvement I'd love to make is throw out all that garbage about EGA hardware. I am somewhat unclear why it got added in the first place. If the only reason is to prevent losing RS232 characters during software scrolling, I hope somebody can attack that problem directly. I would very much like to have 2 scrolling algorithms included, toggled by F3: 6845 hardware, and software. This will make the code cleaner. Any suggestions for making the whole tty business smaller are worth making. I hope the extended keyboard is supported properly. Comments are welcome. V1.3c should run on the PS/2 model 30. When booting, type u or d instead of =. Feedback on this is very much desired. I have no idea about other models. Feedback is sort of desired, but IBM being what it is, I fear the worst.

X| When the PC is powered on, it reads the first block from the floppy
X| disk into address 0x7C00 and jumps to it. This boot block must contain
X| the boot program in this file. The boot program first copies itself to
X| address 192K - 512 (to get itself out of the way). Then it loads the
X| operating system from the boot diskette into memory, and then jumps to fsck.
X| Loading is not trivial because the PC is unable to read a track into
X| memory across a 64K boundary, so the positioning of everything is critical.
X| The number of sectors to load is contained at address 504 of this block.
X| The value is put there by the build program after it has discovered how
X| big the operating system is. When the bootblok program is finished loading,
X| it jumps indirectly to the program (fsck) which address is given by the
X| last two words in the boot block.
X|
X| Summary of the words patched into the boot block by build:
X| Word at 504: # sectors to load
X| Word at 506: # DS value for fsck
X| Word at 508: # PC value for fsck
X| Word at 510: # CS value for fsck

X# bootblok.s is the source of the MINIX boot block. The bootblock is the
X# first 512 bytes on the image file and on the boot diskette. When bootblok.s
X# is assembled, it generates a short binary file (less than 400 bytes) that
X# must be stripped of its header and copied to the file bootblok. The dd
X# command below does this. If everything has been done right, the bootblok
X# file should begin with the following 8 words, in hex:
X# c0b8 8e07 33d8 b8f6 2fe0 c08e ff33 00b9
X# The exact procedure for going from bootblok.s to the binary file stripped of
X# its header is somewhat operating system dependent. Some assemblers make
X# an object (.s) file; others make an a.out file directly. If your boot
X# diskette does not start out by printing 'Booting MINIX 1.0' the problem is
X# probably that you have not made a good boot block.

X The -v "verbose" flag enables you to see what's going on when running
cpdir.
X
X Work yet to be done:
X!
X - link checks, i.e. am I not overwriting a file/directory by itself?

I would very much like to >have 2 scrolling algorithms included, toggled by F3: 6845 hardware, and >software. As the author of the EGA stuff, I now agree that it should go away. The version that is going out with these diffs (assuming ast took my latest changes) should in fact be fairly good about supporting a variety of hardware, but it does so by getting various information about the display adapter, including peeking inside the BIOS to see how many scan lines are needed per character. The problem is that this takes us deeper and deeper into code that is intertwined with the hardware and BIOS. I think there was a time warp, or possibly a lost mail message, because I've already suggested a way to simplify things. However I think it's right not to hold up the release of 1.3c for this. I have promised ast that I'll code up a replacement for the EGA hacks as soon as possible. (I'd also like him to evaluate hannam's proposed code. I can't because testing it requires me to recompile too much code. I don't even have source to elle.) The idea is to avoid depending upon the hardware's ability to wrap at all. Software scrolling of course does this, but at the expense of having to copy the whole screen for every line scrolled. As far as I can tell, all known tty adapters implement the video origin correctly. So there's no problem scrolling for the first few lines using the hardware. It's just what happens when you get to the end of memory that causes trouble. So the obvious fix is to copy the screen just once: when scrolling has gotten to the end of available memory. I conjecture that the overhead of doing this would not be noticable. Software scrolling is unacceptable because when you display a page of output, you have to wait for a big copy operation for every line. If you do the same operation, but only once every 25 or 50 lines, I doubt that anyone would notice. At any rate, even if we had to support both this and the original 1.1 hardware scrolling, the differences could be hidden in a very small section of code, and most of the current cruft would go away. I'm still not entirely sure that I understand the code that hannam posted a week or so ago (attempts to get mail to him seem to have failed). However if it works at all for non-wrapping EGA clones, it works by a slight variant of the same mechanism, where the copying is done a line at a time for the last 25 scroll operations rather than for the whole screen when the end of memory is reach. The amount of data moved would be the same. You should expect to hear more from me in a week or two, after I have a chance to try out these ideas.

Johan Stevenson (the person who was the driving force behind Atari MINIX)
just sent me a very useful little program that combines ls -l and sum. It
is called crc, and the call: crc file1 ... prints for each argument both
the file length and a checksum. The checksum uses a crc algorithm, and is not
compatible with sum. Below is a shell archive containing both the program
and the crc output for the full 1.3 distribution as it is on my Sun workstation
at the university. After you apply all the 1.3 updates, compare your
distribution to this list to see if you got it right. One of these days I
will compare my disk at home (the master machine) with the Sun to see if I
got it right.

XThis file contains important information not present in the book or elsewhere.
XPlease read it VERY carefully.
X
X
X 1. GENERAL
X There were a number of changes made to the code after the book
X was printed. As a result, line X of file Y in the book may actually
X appear at X+3, or X-5, etc. on the disk version. New features have also
X been added in various places.
X
X 2. PC-AT
X The distribution for the PC-AT differs from that for the PC in minor
X ways. For example, there is no /user diskette. Most the files that would
X normally be on /user fit on /usr. Furthermore, the number and organization
X of the source diskettes is different, but the same programs are available.
X Two additional special files are present in /dev: /dev/at0 and /dev/at1.
X These should be used to access 1.2M diskettes. To access 360K diskettes
X on the PC-AT, use /dev/fd0 and /dev/fd1. Special files are used by
X commands such as mount, mkfs, and df, among others. For example, to
X copy part of a 1.2M diskette, type dd if=/dev/at0 of=file count=100.
X The difference between /dev/at0 and /dev/fd0 is that in MINIX, special
X files have sizes to prevent access beyond the end. For /dev/fd0 the
X size is 360K. For /dev/at0 it is 1.2M. Finally, the executable binary
X for the PC-AT contains at_wini.c instead of xt_wini.c (see below).
X
X 3. HARD DISK DRIVERS
X MINIX supports the use of the standard IBM hard disks. Unfortunately,
X IBM chose to use different (and incompatible) disks and controllers on the
X XT and AT. To find out if MINIX works with your disk, give the command:
X dd if=/dev/hd0 of=/dev/null count=1000
X If this runs to the end without errors, the driver embedded in your
X MINIX binary is appropriate for your controller and drive. If it gives
X errors, do a sync, turn the computer off and reboot MINIX. This time run
X a hard disk check from the initial menu. Start MINIX (even if this check
X gives errors). Run dd again. If it still fails, try the following.
X Copy kernel/xt_wini.c to wini.c and recompile the operating system.
X If this fails, then try kernel/at_wini.c and recompile it once more.
X Usually, one of these will work. If neither works, your disk is not
X compatible with either the XT or AT. You will have to modify the driver.
X For PS/2 Model 30 users, a driver ps_wini.c has been provided for use.
X You MUST have a kernel/wini.c to recompile the system, even if you do not
X have a hard disk (in which case, any one will do).
X
X 4. INSTALLING MINIX ON A HARD DISK
X After you have made sure that you have a working hard disk driver, as
X described above, proceed as follows. To use MINIX on a hard disk, you need
X a MINIX partition. You may also have MS-DOS, PC-IX, OS/2, XENIX, or other
X partitions as well if you like. If you understand about making partitions,
X make one any way you are used to. Otherwise use the MINIX fdisk program.
X All partitions on the disk must be an even number of sectors even DOS ones.
X Be warned that the MINIX, MS-DOS, PC-IX, and XENIX parition numbering
X schemes all differ. Be very careful here, lest you overwrite useful data.
X It is suggested that you use the program diskcheck to inspect the MINIX
X partition for bad blocks. The program badblocks will help deal with them.
X The file man_pages in this directory discusses their use.
X Once you have a partition available for MINIX (the type does not matter
X as MINIX does not check), make a file system by booting MINIX from floppy
X the usual way and run mkfs. If, for example, you have chosen partition 2,
X which has, say, 40 cylinders (i.e., 40 x 68 = 2720 sectors or 1360 1K
X blocks), type:
X mkfs /dev/hd2 1360
X to make an empty file system. However, for partition 1 use 1 block less
X because block 0 is not available (it contains the MS-DOS partition table).
X In other words, a 40 cylinder partition 1 has 1359 blocks but a 40 cylinder
X partition 2 or higher has 1360 blocks. Then mount the file system by typing
X /etc/mount /dev/hd2 /user
X Next, make whatever directories you like, typically bin, lib, and others,
X and copy files to the hard disk. With the /usr floppy in drive 0, the
X command
X cp /usr/bin/* /user/bin
X will copy all the binaries from /usr/bin to the hard disk, for example.
X Alternatively, the cpdir program can be used to copy entire trees, e.g.
X cpdir /usr/bin /user/bin
X will create a new directory /user/bin, and put /usr/bin with all its files
X and subdirectories in it.
X A few of the files in /usr/bin must be owned by the root (instead of
X bin) and have mode 4755. Check to make sure. These files are:
X badblocks chgrp df fsck mkdir mv passwd readall rmdir su
X Finally, edit /etc/rc to have the hard disk mounted when the system
X is booted. A line such as
X /etc/mount /dev/hd2 /usr
X can be used as a replacement for the mount command initially in /etc/rc.
X After editing /etc/rc, mount the root file system diskette and copy it
X to the diskette; otherwise the changes will be lost when the system is
X rebooted. (There is nothing special about the root file system except
X its size; it can be mounted and written on like any other file system.)
X After these steps have been taken, the system can be booted from
X floppy in the usual way, and the root file system also read in from
X floppy. The hard disk will automatically be mounted by the /etc/rc.
X The root device remains on the RAM disk, and the boot process still
X goes via floppy (for compatibility and to prevent disaster in the event
X that something goes wrong with the hard disk file system). Hard disk
X file systems can be checked using fsck, the same as floppies. However,
X fsck assumes you have 4 heads and 17 sectors/track. If this is not so,
X change the code accordingly or fsck will give spurious errors.
X The special file /dev/hd0 refers to the whole disk, without regard to
X partitions, whereas /dev/hd1 ... /dev/hd4 refer to partitions 1 to 4. If
X you have a second hard disk, you can make /dev/hd5 ... /dev/hd9 with mknod
X (major device 3, minor device 5 ... 9) for the second drive, with hd5 for
X the whole drive, hd6 for partition 1, etc. Fsck also uses this convention.
X
X 5. CONFIGURING MINIX ON A HARD DISK
X When setting up MINIX on a hard disk, the following set of directories
X is recommended, although the MINIX source tree can go elsewhere if desired.
X Be sure to edit the cc.c program to make sure it knows where to find the
X various compiler passes and libraries, which may be in /bin, lib, /usr/bin,
X or /usr/bin. When a large RAM disk is available, put /bin and /lib on the
X RAM disk, and include the compiler parts in them. When extracting files
X from the distribution, note carefully that there is a lib directory on the
X /usr diskette (for /lib and /usr/lib) and another one among the sources
X (for /usr/src/minix/lib). Many of the directories listed below have sub-
X directories.
X
X /bin - most common binaries
X /dev - special files
X /etc - system administration
X /lib - most important libraries
X /tmp - scratch files go here
X /usr - mount usr file system here
X /usr/bin - rest of the binaries
X /usr/include - system include files
X /usr/lib - rest of the libraries
X /usr/src - sources go here
X /usr/src/minix - minix sources go here
X /usr/src/minix/amoeba - all networking code is here
X /usr/src/minix/commands - utility program sources
X /usr/src/minix/fs - file system sources
X /usr/src/minix/h - operating system header files
X /usr/src/minix/kernel - kernel and device driver sources
X /usr/src/minix/lib - libc.a sources
X /usr/src/minix/mm - memory manager sources
X /usr/src/minix/test - test programs
X /usr/src/minix/tools - tools for building new operating systems
X /usr/tmp - (optional) alternative place for temporaries
X
X 6. PUTTING THE ROOT FILE SYSTEM ON A HARD DISK
X To speed up the boot procedure, you may copy the root file system to
X /dev/hd3 with the commands
X cp /dev/fd0 /dev/hd3 or cp /dev/at0 /dev/hd3
X The former is for the PC, the latter is for the AT. /dev/hd3 must not be
X mounted. When booting, leave the boot diskette in the drive when typing the
X = sign. MINIX will see that the diskette is not a valid file system, and
X take the root file system from the default device, /dev/hd3. You can
X change the choice of default by modifying RAM_IMAGE in fs/main.c
X
X 7. USING MS-DOS AS A DEVELOPMENT SYSTEM
X MINIX is now completely self supporting, so the C86 and PC-IX
X directories have been deleted. The only time you might need MS-DOS is
X for formatting blank diskettes. MINIX does not have a format program.
X
X 8. EDITING LARGE PROGRAMS WITH MINED
X Mined has a limit on the size of programs it can edit. To edit
X larger ones, they must be broken up with split, edited separately and
X recombined later. Better yet, use elle, which is a much better editor,
X is emacs compatible, and can handle files as large as the disk.
X
X 9. MKNOD
X MINIX differs from UNIX in that block special files (and even some
X character special files, such as /dev/kmem) can have sizes. A 360K floppy
X disk special file, such as /dev/fd0 can have size 360K. Unfortunately, the
X mknod system call (and mknod program) have no way to express the size,
X so it uses size 0, which is equal to infinity. When you read past the
X end of a block special file WITH a size, the file system returns zero
X bytes. When you go off the end of a device WITHOUT a size, some drivers
X return end-of-file (e.g., hard disk, RAM disk), but others (e.g., floppy
X disk) return an I/O error code. Thus if you make a new block special file
X for 2/0 and 2/1 (floppy disk) with mknod (i.e., no size) the command
X cp /dev/fd0 /dev/fd1
X will terminate with an error on block 360 (but it will copy the disk
X perfectly). The only way to make a special file with a size is by making
X a file system with mkfs.
X
X10. NONEXISTENT DEVICES
X If you try to open /dev/fd1 on a system with only one floppy disk drive,
X the system may hang. To avoid this problem, the first time you log in, go
X to the /dev directory, and rename special files that you do not have to
X something unusual. For example, if you do not have a hard disk, rename
X hd0 to HARD_DISK_0, hd1 to HARD_DISK_1, etc. Similarly with one one floppy
X disk, rename fd1 to FLOPPY_DISK_1 to prevent it being typed by accident.
X You can also remove them, but due to the mknod problem described above, you
X can not get them back easily, so it is best just to get them out of the
X way in case you ever need them again later.
X
X11. PRINTER
X In order to accommodate buffered and unbuffered printers, the printer
X driver uses a combination of delay loops and interrupts. The net result
X is that the driver consumes a fair number of CPU cyles when running. If
X you expect to do a lot of printing, you might want to consider rewriting
X the printer interrupt handler, pr_char, in assembly code. Note that some
X printers that are not IBM compatible give spurious out-of-paper messages.
X
X12. DISK SPACE
X The /usr disk as distributed is nearly full. If you have two floppy
X disk drives, be sure to mount /user on drive 1 and move your working
X directory there. If you have only 1 floppy disk drive, remove some files
X from /usr/bin to make more space. If you have a hard disk, there is no
X problem.
X
X13. RUNNING /USER TESTS ON A FLOPPY
X Before running the tests in /user/test, remove the files in
X /user/commands to create some free space on the disk. Run the tests as
X superuser.
X
X14. COMMAND LINE LENGTH
X The maximum initial stack size is 2K. Calls to EXEC which require a
X larger stack will fail. Thus if you do ls -l * in a large directory,
X the shell may expand the * so that the command line exceeds 2K and the
X EXEC will fail, resulting in a message such as "Cannot execute ls".
X
X15. ARCHIVES ON THE DISTRIBUTION DISKETTES
X To save space on the distribution diskettes, some of the sources have
X been archived and compressed. Files ending with .Z are compressed files,
X and can be decompressed by typing: compress -d file.Z
X In some cases, the resulting file is an archive, ending with the .a suffix.
X Remove the files with: ar xv file.a Thus a file like fs.a.Z must first be
X uncompressed to get fs.a and then dearchived.
X
X16. RECOMPILING FSCK AND OTHER LARGE PROGRAMS
X If for some reason you don't like the tools/fsck binary and want to
X recompile it, make sure you have plenty of free space for the compiler's
X temporary files. On a floppy disk system, this may mean putting fsck on
X an almost empty diskette before compiling it. When the disk is full, the
X quality of the compiler's error messages deteriorates rapidly. If you
X are compiling fsck and getting strange results, check for disk space.
X Normally /tmp is used for temporaries, but the -T flag can override that.
X
X17. NEWS GROUP
X If you have access to USENET, you may be interested in knowing
X that there is a news group, comp.os.minix devoted to discussions of MINIX.
X This is one of the largest news groups, with over 10,000 readers.
X If you have access to the Arpanet, Bitnet, or EARN, the news group is
X gatewayed there. Contact info-minix-request@udel.edu to join or send
X email to ast@cs.vu.nl requesting the MINIX information sheet.
X
X18. SYSTEM PROBLEMS
X The IBM PC does not have any hardware for checking for stack overflow.
X The user must allocate the amount of stack for each program with chmem
X or use the compiler default (64K - program - data size). Some programs
X in the distribution have been set to a smaller value, and may, in rare
X instances with certain arguments, hang. If the system ever gets into a
X situation where it echoes keystrokes, but ignores DEL and CTRL-\ and
X appears otherwise to be hung up, hit F1 to see what is going on. If
X some process is running and there is no way to interrupt it, hit CTRL-F9.
X This key is equivalent to the super-user typing: kill -1 9. The result
X of CTRL-F9 is that every process in the system is killed, including update
X and all the shells. Although drastic, CTRL-F9 will dehang the system
X instantly. Log in again and then type /etc/update & to restart update.
X The reason for requiring CTRL to be held down while hitting F9 is to
X prevent F9 from being hit by accident.
X
X19. USE OF EXTENDED MEMORY ON ATs
X If the size of the root file system (either taken from floppy or from
X /dev/hd3, as described above), is 256K or more, MINIX puts the root
X device in extended memory, above 1M, leaving the entire 512K or 640K
X free for MINIX and user programs. To get full advantage of the extended
X memory, the size of the root file system should be the same as the amount
X of extended memory present. If the root file system is < 256K, MINIX
X assumes that there is no extended memory, and puts the root file system
X in "low" core (below 640K). This feature only works on ATs, so PCs must
X never have root file systems >= 256K. If you have a large extended memory,
X you may want to put the root file system on hard disk, as described above,
X so the extended memory can be loaded from hard disk quickly at boot time.
X
X20. SOFTWARE SCROLLING FOR EGA CARDS
X MINIX works with monochrome cards, CGA cards, and IBM compatible EGA
X cards. However, it does not work with some nonstandard EGA cards. With
X some cards, the screen will go blank every 25 lines. MINIX can be made to
X work with these EGA cards by hitting the F3 key to use software scrolling.
X This is slower than hardware scrolling, so only use it if you have to. You
X can toggle between the two modes by hitting F3 repeatedly. If you want soft
X scrolling to be the default, recompile kernel/tty.c with the variable
X softscroll initialized to 1, and make a new kernel.
X
X21. NEW FLAGS AND FEATURES
X Various programs have acquired new flags and features and new programs
X have been included. Please read all the files in this directory carefully.
X
X22. ANSI ESCAPE SEQUENCES
X The escape sequences used by the tty driver for both input and output
X have been changed to the ANSI standard ones. To manipulate the cursor
X etc., print the following (among others):
X ESC M: scroll a line backwards (cursor must be on line 1)
X ESC [ y ; x H move to column x, row y; (1,1) is upper right corner
X ESC [0J clear from cursor to end of screen
X ESC [7m go to reverse video
X ESC [0m go to normal video
X
X The 9 numeric pad keys, as well as numeric + and - now generate ESC [ x
X for some x. Just type them to see which x goes with each key. There is
X an /etc/termcap file for MINIX that uses the allowed sequences.
X
X23. _CLEANUP NO LONGER NEEDED
X The exit routine has been changed to call _cleanup automatically.
X As a result, programs using stdio no longer have to call it explicitly.
X All calls to _cleanup have been removed from the standard distribution.
X
X24. DISTRIBUTION CHANGES
X The subdirectories PC-IX and C86 have been deleted, as mentioned above.
X In a few cases, a subdirectory IBM_PC is present for files specific to the
X IBM PC/XT/AT/386 version of MINIX (as opposed to the Atari ST). These files
X should be moved up one directory level. In some cases, two makefiles are
X provided, called pc_makefile and at_makefile. Copy the appropriate one to
X makefile, depending on whether you have (1) a PC or XT or (2) an AT.
X Study them both and delete the inappropriate one. The differences are
X usually related to the assumed size of the RAM disk, rather than any
X differences between the two processors.
X
X25. LINKS
X The directory /usr/include now contains several subdirectories and also
X linked files. If you copy this directory to hard disk, link the following
X files, if possible.
X
X /usr/include/sgtty.h to minix/h/sgtty.h
X /usr/include/signal.h to minix/h/signal.h
X /usr/include/minix/callnr.h to minix/h/callnr.h
X /usr/include/minix/com.h to minix/h/com.h
X /usr/include/minix/const.h to minix/h/const.h
X /usr/include/minix/type.h to minix/h/type.h
X /usr/include/sys/stat.h to minix/h/stat.h
X /usr/include/fs/buf.h to minix/fs/buf.h
X /usr/include/fs/const.h to minix/fs/const.h
X /usr/include/fs/super.h to minix/fs/super.h
X /usr/include/fs/type.h to minix/fs/type.h
X
X In addition, the files dosread, dosdir, and doswrite in /usr/bin should all
X be links to the same file. It determines which it is by looking at argv[0].
X
X26. LACK OF SPACE
X If you are running on a system with limited memory, either 512K RAM
X or no hard disk, you may encounter difficulties trying to recompile the
X system. However, there are steps you can take to improve the situation.
X First, various passes of the compiler are configured with ample stack
X space. Using chmem you can reduce this stack space to reduce the program's
X memory requirements. Be careful about not reducing it too much, or strange
X things will happen. Second, the compiler flag -T can be used to place
X temporary files in a place other than /tmp. This flag may be useful if
X /tmp is on the RAM disk, which is too small. Third, the compiler flag -F
X can be used to run cpp and cem sequentially instead of in parallel. This
X approach is slower but uses less memory. Fourth, the library, libc.a
X contains several large routines that are rarely used. By removing these,
X you can reduce the amount of space the library requires. Fifth, if you are
X able to compile but not link, after having created all the *.s files, you
X can remove some of the larger *.c files, replacing them with null files to
X keep make happy, and then link. Sixth, the size of the RAM disk is
X determined by the size of the root file system. If the default size is not
X suitable for your configuration, you can make a new root file system with
X mkfs. In particular, on an XT, you may wish to move cpp and cem from /lib
X (RAM disk) to /usr/lib (hard disk), thus making it possible to build a new
X and smaller RAM disk to free up more "core." If you do this, be sure to
X modify cc.c, since it has to know where to find cpp and cem.
X
X27. MULTIPLE BIN DIRECTORIES IN THE DISTRIBUTION
X Since the distribution disks are nearly full, a few of the programs that
X logically ought to be in the /usr/bin directory have been put on one of the
X other distribution diskettes in a separate bin directory. On a hard disk
X system, these programs should be put in /usr/bin.
X
X28. LIBRARY
X Not all the sources in minix/lib have been included in libc.a (to save
X space). If you have a hard disk and enough space, compare the sources and
X binaries and add the missing files. Remember to compile all library
X routines with cc -c -LIB file.c. The -LIB flag is essential for libraries.
X The library sources are contained in the lib/libsrc.a archive.
X
X29. RS232 LINES
X MINIX supports RS232 lines to terminals and modems. Baudrate, parity,
X and bits/character are user settable. The special files /dev/tty[12] are
X used to access the RS232 lines. They can be opened for reading and writing.
X As shipped, the system is configured for only one line, /dev/tty1. To
X enable the second one, change NR_RS_LINES in tty.c to 2. Doing so will
X increase kernel size by 1K, due to the extra table and buffer space needed.
X The file /etc/ttys can be configured to have a shell be started for
X either line, thus making MINIX a multi-terminal system. The second char
X of the three-character /etc/ttys entry gives the line parameters. See
X the comment at the start of tools/init.c for details.
X The program stty can be used to set baud rates, bits/character and
X parity for its standard input, e.g. stty 9600 8 -even -odd </dev/tty1
X sets line 1 to 9600 baud, 8 bits/char, no parity. The stty program does
X its work using the ioctl system call.
X
X30. MISSING SOURCES
X The sources for the C compiler (including all its parts), the editor
X elle, and patch are not included in the distribution. The compiler sources
X are available from Transmediair and UniPress (see below). The elle and
X patch sources were too large to be included and are only available via the
X USENET online archives.
X
X31. C SYMBOL TABLE
X A new flag, -s, has been added to cc to generate a symbol table in the
X a.out file. It can be printed using nm and removed using strip. Do not
X confuse -s (lower case, symbol table) with -S (upper case, assembly code).
X
X32. PASCAL AND MODULA 2 COMPILERS FOR MINIX
X A MINIX compiler for Pascal is available. A MINIX compiler for Modula 2
X will available during the course of 1988-9. Neither is part of the standard
X distribution. They may be purchased from either of:
X

X+ chmod a-w file # Make file read only
X+ chmod u+s file # Turn on SETUID for file
X+ chmod g=u # group perms set to same as user perms.
X+
X+ The given mode is applied to each file in the file list. The mode can
be
X+ either absolute or symbolic. Absolute modes are given as an octal number
X+ that represents the new file mode. The mode bits are defined as follows:
X+ 4000 Set effective user id on execution to file's owner id
X+ 2000 Set effective group id on execution to file's group id
X+ 0400 file is readable by the owner of the file
X+ 0200 writeable by owner
X+ 0100 executable by owner
X+ 0070 same as above, for other users in the same group
X+ 0007 same as above, for all other users
X+
X+ Symbolic modes modify the current file mode in a specified way. They take
X+ the form:
X+ [who] op permissions { op permissions }
X+ The possibilities for [who] are 'u', 'g', 'o', and 'a'; standing for user,
X+ group, other and all, respectively. If who is omitted, 'a' is assumed, but
X+ the current umask is used. The op can be '+', '-', or '='; '+' turns on the
X+ given permissions, '-' turns them off; '=' sets the permissions exclusively
X+ for the given who. For example 'g=x' sets the group permissions to '--x'.
X+ The possible permissions are 'r', 'w', 'x'; which stand for read, write,
X+ and execute; 's' turns on the set effective user/group id bits. 'u',
X+ 'g' and 'o' in the permissions field stand for the current user, group, or
X+ other permission bits, respectively. Only one of these may be used at a
time.
X+ 's' only makes sense with 'u' and 'g'; 'o+s' is harmless and does nothing.
X+ Multiple symbolic modes may be specified, separated by commas.

X! Then go to the mm directory (ie. ../mm) and type:
X! make clean
X! Then go to the kernel directory (ie. ../kernel) and type:

X! 3. Go to the amoeba/mm directory and run make.
X
X! 4. Go to the amoeba/fs directory and run make.
X
X! 5. Go to the amoeba/kernel directory (NOT the regular kernel directory).
X! If you do NOT have an ethernet card but still wish to have local Amoeba
X! transactions then edit the makefile and add -DNONET to the CFLAGS.
X! If you do have an ethernet card and would like to keep ethernet
statistics
X! then add -DSTATISTICS to CFLAGS.
X!
X! 6. Now run make.
X!
X! 7. Go to the tools directory and build a new boot floppy.
X! The command to do this is:
X! make net
X!
X! 8. Reboot your machine using the new boot floppy.
X!
X! 9. Test the system. The directory amoeba/examples contains several programs
X to test the reliability of transactions. The READ_ME file in the
directory

X You must do the following important steps carefully.
X
X
X! 1. Make sure that you are in the amoeba directory and that there is plenty
X! of free disk space. Run the command:
X
X install
X
X! 2. Type: make
X
X! 3. When you are instructed to do so, insert a blank diskette and hit return.
X
X! 4. Reboot your machine using the new boot floppy.
X
X! 5. Test the system. The directory amoeba/examples contains several programs
X to test the reliability of transactions. The READ_ME file in the
directory
X gives more details.

X! found that the chip on the ethernet card was so much faster than the CPU
X! on the Zenith AT clone that it was always sent before the next packet is
X! ready. If necessary the high level code busy-waits until the ethernet
X! write buffer is free. If write interrupts are required then pkt_sent()
X! in amoeba.c should be modified.
X! This is rather disgusting, but was done for efficiency reasons.
Interrupt
X! handling is expensive under Minix and so it was much faster to not
X! generate interrupts and just wait for the buffer to become free.

and
X! waiting for an interrupt. By the time the context switch was done, the

to
X! just wait for it. On a very slow machine, a different strategy might be
