Subject: COMMAND.COM lost during Backup/restore
Dear readers,
I possess an IBM AT computer with an original 20 MB hard disk and another
45 MB hard disk. Both disks are booted form the original one - drive c -
and were formatted together by a softwere called Vfeature Deluxe. I was
told that the 45 MB disk is significantly faster than the original one.
Each time I backup drive c (the original), by BACKUP /S Dos command, as
soon as I finish the backup I lose the command processor together with
many files on this drive. When I restore the system and all of drive c,
after installing the system files, by RESTORE /P, drive c is fine, but
there is no connection to drive d. It turns out that IBMBIO and IBMDOS of
my backup ARE DIFFERENT than the original DOS files in the Dos diskette.
If I replace the original system files with those of my backup diskette I
get back a connection with drive d and everything is fine.
There can be two possibilities:
1. Vfeature program changes IBMDOS and IBMBIO files, which become
incompatible with the BACKUP program.
2. I have a virus that modified these system files, which shows its
presence when I perform a complete backup of drive c and otherwise lives
"in symbiosis" with the modified system files and the other programs.
Did any reader of this note encounter a similar phenomenon and can inform
me of the true reason?
Sincerely,
Michael Maschler

Is there a fileserver (LISTSERV ?) somewhere that is accessible for getting
missing issues of the digest? Gateways have been fragile over the past few
months, and I am missing issues I'd like to obtain. I'd appreciate sug-
gestions for how to reach the fileserver best from uucp or BITNET location.
Thanks,

>Re: program updates
I got bug reports from Rahul Dhesi on two files I had uploaded to
SIMTEL20. I have now fixed the problems, and have uploaded the
revised files to SIMTEL20. Here are revised blurbs...
PD1:<MSDOS.C>GETF.ARC
BLDFUNCS scans one or more C source files and notes where each
function is defined. GETF is then used to locate the source file
containing a particular function and direct your favorite editor to
it. The system is particularly helpful when editing someone else's
large program which is divided into many files. The ARC file
includes source code, executables, and documentation for both.
BLDFUNCS now accepts wild cards on the command line.
From Marvin Hymowech's article in DDJ #142 (August 1988),
transcribed and modestly enhanced by James R. Van Zandt
<jrv@mitre-bedford.arpa>.
PD1:<MSDOS.TROJAN-PRO>FILE-CRC.ARC
FILECRC calculates CRCs for all files on a disk and records
them in a file. COMPARE then compares two such files and
reports differences, highlighting suspicious changes (file
contents changed but creation date unchanged). Useful for
spotting viral reproduction and/or damage. Both programs now
allow users to change the parameters at run time. FILECRC also
now traps control-C so it does leave file attributes changed if
it is interrupted. This ARC includes source code, executables,
and documentation for both. Written by Ted H. Emigh,
translated from Pascal to C and modestly enhanced by James R.

Subject: Movebp Problem (MOV [BP-disp],AX) (3 msgs)
A friend wrote a large FORTRAN program. After some changes it would not
run. I found the problem in a DO loop that didn't stop at the right time.
The code was correct (I beleive so), but mov [bp-2e],ax didn't work. Can
anyone tell me, what's happening there?
small piece of code (for DEBUG) follows:

Subject: what is a processor doing whith MOV [BP-disp],AX?
Toad Hall Note:
I received the above message and hacked a little test program to see just
what was going on. The code below replicates (I believe) the DEBUG session
Reinhold enacted.
When I compile this code (into a .COM program) and step through it
in SYMDEB, all instructions (via the 'u' command) are EXACTLY what Reinhold
got in his DEBUG session. So .. it hasn't compiled strangely, picked up
any segment overrides, or whatever.
One difference from Reinhold's experience, however: it works perfectly!
SS:733CH (the same place as SS:[bp-23H] when BP = 763AH) starts off as 0
before the AX stuff (in my system anyway), and changes to 1234H when I
stuff
AX (mov [bp-2EH],ax).
So .. I donno WHAT's going on in Reinhold's system! My XT clone
(8MHz 80286) running PC-DOS 3.1 runs that code perfectly.
Reinhold, you DO have real memory at that SS segment, right? Can't im-
agine why a ROM would be sitting there (which wouldn't permit a write to
it). Donno WHAT memory would 'look' like if you had less memory than 640Kb
and that SS segment was empty.
Just as a note, when programming in assembler, I routinely disable inter-
rupts (via the CLI instruction) before I fiddle SS, but that really
shouldn't matter here or in your Fortran code .. might be kinda hard to do
in Fortran anyway .. donno.
Regrets I can't be of more use with a real fix .. a 'no problem' report
isn't very helpful, is it?
See beyond the test assembler code for my SYMDEB dump of the test
program.

Subject: movebp problem
I think the problem is real simple now. I made some tests with the original
program and found, that the generated code had some errors.
We use an old IMSL-Library (no source code avail., compiled with MS-FORTRAN
3.20). So we have to use compiler switch /Gr (MS FORTRAN 4.10), for saving
DI and SI. (3.20 didn't)
if(string1.eq.string2) then
........
endif
generates code that calls __FCccmp and then POPs DI and SI, without having
saved them before. So for every string compare SP increases by 4 (wrong
code).
MOV [BP-2E],AX works correct, but BP-2E=SP-4 !! (SP is wrong). If an Inter-
rupt occurs (timer,...) this place is used for the return address. For a
long loop (p-command in SYMDEB) we will see the return address of the last
interrupt, that had overwritten the original contents.
and don't forget /Od:
x(i)=a/b
a=b
c=x(i)
write(*,*) c

Subject: Stand-alone XMODEM query
(He wants a "stand-alone" xmodem that could be executed by itself without a
peripheral package like Kermit."
I'd suggest DSZ.COM (which is available from SIMTEL20's <msdos.zmodem>
subdirectory. It has a sufficient number of command line parameters to
permit xmodem (checksum or CRC) sends or receives of desired file to
desired COMM port at desired speed .. which is what you're trying to do,
ne?
I also have a wee little .COM program that does simple xmodem sends and
receives .. but no source, and only checksum mode (no CRC).
In the long run, I'd say use DSZ because of its greater variety of
protocols, port flexibility, support, etc. And by all means, register and
get the ZMODEM protocol enabled.
Hope this helped.

Yes, UUPC will move the news articles into your machine, however, you
still need a news-reader on the PC to read them.
Now, my question is, does anyone have a functional news-reader for the PC
yet? If not, would some people like to get together and write or port
one?

DATABASE@BITNIC archives individual articles and makes them available for

I need help with Btrieve 4.03a (and a Turbo C program) and an alternate
collating (sort) sequence. I have written a program for a German user, and
need to sort a string key on an alphabet expanded to include the seven
additional German characters (A,a,O,o,U,u with Umlaut and ss). I am using
an IBM XT, and German keyboard and the KEYBGR program. The UPPER.ALT
supplied as an example only replaces each lower case alphabetic with it's
upper case equivalent; I need to insert the umlauted letters after their
un-umlauted partners.

Subject: COMMAND.COM patch for DOS 3.3
Just recently I read (here, I think) about the now infamous patch for DOS
to expand the environment space. Then, I didn't care ... after all, I use
the SHELL command in CONFIG.SYS to set up a large environment.
Then yesterday I had to install a menu system for a user ... guess what
... it obviously uses the DOS EXEC call to dispatch programs, and this
call only gives you the default environment!
SO .... would some kind sole please repost the patch to MS-DOS 3.3 to
expand the environment?
Thanks

The easiest way to expand the environment is to use the SHELL command as
follows:
shell=c:\command.com /p /e:xxx (where xxx is the desired size of the
environment in 'paragraphs') ...
Put that line in your 'config.sys' file

I have been using "Numerical Recipes In C" which I HIGHLY recommend. You
would need to buy both the book and the diskette. The book is essential
since it is the documentation for the routines, but it is more than that.
The book is an extremely readable and informative guide to the numerical
techniques used---both their redeeming qualities and their pitfalls. It
is published by Cambridge Press and any bookstore should be able to order
it. University bookstores seem to keep the books and diskettes in stock.
(There is another book for Fortran and Pascal and associated disks.) The
book and diskette together should cost about $60. Quite a bargain in my
opinion.

Subject: Hand Scanners
I would appreciate hearing from anybody who has had EXPERIENCE using
some of the low-cost hand scanners on the market. I am aware of and have
read the recent PC Magazine article but am interested in real-world use.
The main application is a low-cost Fax setup with a FAX board, a Laser or
Deskjet printer, and the hand-scanner for capturing digitized images of
the documents (the more expensive, oCR-enabled scanners are not that
important, just the pictures). In particular, how difficult is it to get a
cohesive image of an 8.5 x 11 page with the narrow width scanning that
these things appear to have, or are they practically limited to pictures
and book pages ?
Thanks for any assistance [and feel free to comment on any experience
with the FAX boards - and I know about PC's reviews of them too].

Subject: IBM Laptop Hard Drives
Laptop PC Users:
I want to add an external hard drive to an IBM Convertible laptop
computer (also known as the "Clamshell"). The machine is a "model 2" with
640K RAM, serial & parallel slice, supertwist LCD screen.
I have found many vendors of both internal and external drives for
more popular laptops (e.g. Toshiba, NEC, Zenith). However, I have only
identified one external drive vendor for the Convertible. The company
wanted about $900 for a 20 megabyte external drive (with 65ms access
time).
To cut costs, I would like to build my own external drive from
inexpensive common components, e.g. Seagate drive, case, power supply,
etc. Hopefully, I could address the drive through the serial or parallel
ports. I want to avoid having ribbon cables coming out the CPU box.
Here are some questions maybe you hardware specialists or Convertible
users could answer for me:
1) Is the project feasible, especially addressing a hard disk through
the existing serial/parallel port?
2) Could I keep the total price under $500?
3) Would new system ROMs be required?
4) Has IBM produced a Convertible ROM update lately supporting hard
drives?
5) Does IBM sell an external hard drive kit for the Convertible?
6) Are there alternate ways of going about this effort?
Please E-mail all responses directly to me at the address below.
Thank you for your assistance.

Subject: Info-IBMPC Digest V7 #58 (about Mice)
Some more information about mice:
Recently a new breed of mice has arrived, the so called "hi-res" mice.
These send more "ticks" to the computer for a given distance of movement:
technically, they have more mickeys/inch. The upshot of which is that you
don't have to move your wrist as far to get the same amount of cursor
movement on the screen; they are more sensitive. These mice are being
marketed as the new state-of-the-art which no power user should be
without.
About mice interfaces: They all communicate at 9600 baud with their
controllers, in some cases through a serial port and in others a parallel
port. The parallel ports are recently being included on other boards, eg.
I believe the VGA Wonder has one.
The most important thing to watch for when mouse-shopping is that there is
a reputable company supporting it. This is because every once in a while
Microsoft makes teensy- weensy changes in their mouse driver, and
everybody else has to jump to make theirs compatible. Reputable comp-
anies (ie. Logitech and Mouse Systems) will ship you an updated mouse
driver when you call them over the phone, for free. "Clone" mice will not
have this level of support; in this case it's important to get one that is
100% hardware compatible so you may use someone else's software. (Of
course this is not legal.)
Furthermore, the mouse-makers are offering lifetime or long-time
warranties on their products.
Mice make fun holiday gifts. So do mouse pads :-) Logitech tends to be
the cheapest brand, but this is not to say their product is inferior; it
is not. Merely different. Mouse Systems has to include a pad with their
(optical) unit. This year, Logitech has a clear-case version of their C7
mouse for sale.

Subject: Movebp Problem (MOV [BP-disp],AX)
If you look closely at the code being traced, you will see that BP-2E is
four bytes ABOVE the top of the stack, and thus gets clobbered on every
interrupt--be that the timer tick, the keyboard interrupt, or the INT 3
instruction DEBUG uses to implement the P command. What happens is this:
MOV [BP-2E],AX SP -> xxxx
SP-2 -> xxxx
BP-2E = SP-4 -> 1234
interrupt to DEBUG SP -> xxxx
SP-2 -> flags register
BP-2E = SP-4 -> CS
new SP = SP-6 -> IP
DEBUG runs, uses even more stack space
...
MOV AX,[BP-2E] SP -> xxxxx
SP-2 -> flags from call to DEBUG
BP-2E = SP-4 -> CS from call to DEBUG

I am trying to set up a two-monitors system. One monitor is the hercules,
which is also the system monitor, and the other one is a CGA, which sends
output to another display. The purpose is to develop programs on the
hercules, and to view the graphical output on the CG, so that the graphs
will be displayed all the time of program run. To do that, I have to
address the CGA directly, since DOS won't allow two monitors system (at a
given monent). I found out that I have to have the corect numbers to be
programmed into the CRT controller on the CGA adaptor. In short, whet I
need is the information regarding the initialization of the CGA for
graphics. I know also that DOS interrupt #10hex does similar services, but
I do not have any information about this interrupt.
If someone have any experience with similar task, or have information how
to initialize CGA board for graphics, or information about DOS interrupt
10hex, It will be most appreciated.

Borland's "Turbo Numeric Toolbox" (really "Turbo Pascal Numerical
Methods") is a Turbo *Pascal* add-on! You get source, so you'd presumably
be able to port by hand to C. I don't know if it contains TP 4.0 or 5.0
.LIB files, which you could call from C.
The Programmer's Connection catalog lists something called the C Math
Toolbox from Silver State Software (list $89, PC $85), but there's not
much info on what it does. Ditto for Lattice's SSP/PC Scientific
Subroutine Package (list $350, PC $269). Call PC at 216-494-3781

Subject: Writing to EGA Memory Problem
I am working on an application that writes directly to video memory. The way
that this is accomplished is shown below:
#define SCREEN_MEMORY 0xB0000000L /* screen memory map address */
#define SCREEN_COLUMNS 80 /* 80 columns */
#define SCREEN_ADDRESS (line, column) (char *)(SCREEN_MEMORY + \
((line - 1) * SCREEN_COLUMNS + \
column - 1) * 2)
Recently it was decided to upgrade this program to run on an EGA equipped
machine. This changed the code to:
#define SCREEN_MONO_MEMORY 0xB0000000L /* screen memory map address
for mono display */
#define SCREEN_COLOR_MEMORY 0xB8000000L /* screen memory map address
for color display */
#define SCREEN_COLUMNS 80 /* 80 columns */
#define SCREEN_ADDRESS (line, column) (char *)(SCREEN_MEMORY + \
((line - 1) * SCREEN_COLUMNS + \
column - 1) * 2)
SCREEN_MEMORY was changed from a constant to a variable set to the appropriate
memory address.
Everything works great while I am in the program, but when I exit from it,
(while on my EGA equipped machine) any routine that does anything
significant to the screen (editor, screen color changer) causes the
machine to lock-up and I must re-boot. (Warm boot works ok). On the mono
eqipped machine the program works fine and when I exit everything is ok.
There must be something I need to reset or save in the program but I don't
know what it is. Can someone shed some light on this for me?
Thanks for your assistance,
