Several people replied to my query about getting an 80Mb drive to
work under SCO Xenix (thanks!). They all pointed me at:
Golden Bow Systems
2870 Fifth Avenue
Suite 201
San Diego, CA 92103
Golden Bow sells a ROM that sits in the gaps around the BIOS ROMs and
patches in its own tables over the standard BIOS disk type tables.
It comes with a program that you run to select the drive parameters.
I ordered one over the phone, it showed up 3 days later, and I got
Xenix running that day. I've partitioned my disk into a 100 cylinder
DOS partition and a 9900 cylinder Xenix partition, and everything
works fine.
The ROM is called 'DUB14' and costs about $100. I obviously don't have
any association with Golden Bow or I wouldn't have had to ask about
this in the first place...

From: jcmorris@mitre.ARPA
The best file comparison I've used isn't free, but it's close to that
and (believe it or not) comes from IBM. The "Personally Developed
Software" catalog lists the SUPERC program, which provides menu-based
comparison at the file, line, word, or byte level with numerous
variations (column limits, etc.). I don't have the catalog handy, but
I think it's about $30 or so. If you can't find a catalog, call
1-800-IBM-PCSW and order either the catalog (free) or the software
(MC/VISA).

Subject: Hercules in a Compaq
A while back I posted a few messages asking for help in getting a
Hercules monochrome graphics board or equivalent board to run in a
Compaq portable. I did finally succeed, but it wasn't easy.
First, the Compaq disk controller board and the Hercules monochrome
board both have LPT1 ports, neither of which can be disabled or
switched to LPT2. Hercules tech support suggested using their new
board which has a parallel port which can be disabled, or a rather
drastic hardware modification which would void the warranty. We opted
to exchange the Hercules board for a clone from Classic which also
allowed disabling the port (or at least the second one did when we got
the correct board revision).
Next, we wanted to remove the Compaq video board entirely to free up
the slot. Compaq tech support claimed that there should be no problem
with doing this with any BIOS version, as long as the motherboard
switch was set properly, but in fact we had to get a BIOS upgrade in
order to boot in this configuration.
Finally, we found that many pieces of software seemed to switch to the
(disconnected) internal monitor. Typing MODE MONO would switch back,
but this didn't help in the middle of a program. A little
experimentation with DEBUG showed that INT 10h calls for 80x25 color
or B&W mode setting both switched to the internal monitor, while INT
10h with AX=700h switched back to the Hercules clone. Perhaps I'll
understand why when my Compaq tech reference manual finally shows up;
this seems to be an undefined function call in my IBM documentation.
So, I wrote a simple resident routine to intercept INT 10h and
translate AX=200 or 300h to AX=700, and finally everything seems to
work. I could send the source code to the net, or is this to obscure
a problem to interest anyone else?

Subject: Selective COPY, DEL, and TYPE
Date: Thu, 06 Nov 86 16:52:51 -0500
From: Mark Colan <mtc@ATHENA.MIT.EDU>
The cleanest way to do this would be to write a simple "C" program
which would expand the file name list and execute the command for
each expanded file. In Lattice C 3.10 you can easily expand files
with the dfind / dnext calls, and execute a command via system().
But there is a challenge here: to do it entirely in .BAT programming.
I've come up with one (admittedly dirty) solution using .BAT commands.
You need the following two .BAT files, and the ASK program from
info-ibmpc (DOS does not provide any means of asking for a reply in .BAT
files, so the ASK program is unfortunately necessary). Here are the two
BAT files:
SELECT.BAT
echo off
for %%f in (%2) do command /c select1 %1 %%f %3
SELECT1.BAT
:select1
echo off
ask "%1 %2 %3 ? " ny
if errorlevel = 2 goto doit
goto dont
:doit
%1 %2 %3
goto done
:dont
echo %1 %2 %3 NOT done.
:done
(If you don't have the ASK program yet, get ASK.ASM from usc-isib:<info-ibmpc>
and build it with the following commands, which are not listed in the ASK.DOC:
MASM ASK;
LINK ASK;
EXE2BIN ASK;
REN ASK.BIN ASK.COM
)
The BAT files are set up to allow the use of ANY command, DOS or otherwise,
that has one or two arguments. It would be easy to make this work with
commands up to 8 arguments by replacing all occurences of "%3" with
"%3 %4 %5 %6 %7 %8 %9" in both files. To use SELECT, just precede the
command with your desired template with the word SELECT. For examples:
To DELETE files:
select del *.c
To COPY files:
select copy foo??.* \bar
For each matching file (using any valid DOS template) it will type out the
full command it is going to do, followed by a "?". You reply with "y" or
"Y" if you want the action to occur; anything else is the same as typing
"n".
MISFEATURES:
1. Unless you have your COMMAND.COM patched to permanently turn off ECHO,
you will see "ECHO OFF" twice before it asks the big question, for
each file. Any clever hackers out there know how to avoid it without
the patch?
2. If you want to quit, you can't, until it has asked for each and every
matching file. You will have to hit "n" or "Enter" for each question
it asks. Even ^C or ^Break does not exit very well.
3. This still requires a program from INFO-IBMPC library, which this request
asked to avoid.
SUGGESTION:
To play with these commands, use the "ECHO" command: SELECT ECHO *.*
This command has no effect except for writing a message on your screen,
so its less troublesome than playing with DEL.

I assume you have put a SHELL= command in your config.sys file to get
dos to reload command.com from drive C:. Did the shell command
include the /P option? This is required if you want it to run
autoexec.bat automatically. The full syntax would be:
SHELL=C:\COMMAND.COM C:\/P/E:nnn assuming your command.com is on the
root dir of drive c:. The /E:nnn option is for setting the size of
the environment. Just leave it off if you don't need it.

Subject: QUBECALC, AnalytiCalc, ...
I've seen Qubecalc on the DEC Market system and ran a test a couple
days ago of a 20 by 20 heat transfer model (each cell the average of
itself and its 8 neighbors, with boundary conditions). The package ran
nicely and updates displays very quickly. For folks who want a
spreadsheet for truly 3 dimensional applications, this package gives a
usable engine. Online help is also quite well done.
In comparison, AnalytiCalc, which is also available on the
Simtel20 system and on Market, is a 2D 18000 by 18000 sheet with links
to other sheets permitted. It offers a cruder help system but lots of
functions you won't see elsewhere like FFTs on screen, matrix math, 8
dimensional equation fitting, multiple equations per cell, etc....
The 20 by 20 test took 58 seconds for QubeCalc to recalculate
once (on a 6MHz AT). It took AnalytiCalc 14 seconds to do the same
problem. AnalytiCalc uses DOS (!) or the BIOS for screen writing, so
appears slower. Evidently there's some penalty for having all the 3D
logic. Still, QubeCalc handles 3D problems much more smoothly than
conventional architectures. Cells are referred to as Rk;l;m or Ak;l;m
where k;l;m are the x, y, and z coordinates of cells. These are
numbered 0 to 63 and seem to have recursive boundary conditions (so 0
and 63 are neighbors) though I didn't play much with this, so I don't
know about in formulas.
Either package appears to be considerably more powerful than
the other PD spreadsheet systems, and both have features that
commercial packages lack. I'd suggest that for most applications you
may want to look at AnalytiCalc. The DEC Market system (617 467 7437;
login LCG.KERMIT KERMIT) has AnalytiCalc in the MSDOS: area and
QUBECALC in the PCDOS: area, both archived.

The archive file of QubeCalc on SIMTEL-20 is alright now. Apparently
some people have been getting a bad header message when dearchiving it
(I got the same message when I dearchived it). This message doesn't
appear to have any affect on the program or associated files, though.
I'm removing the copy from my directory on the KL so you'll have to
get it from SIMTEL from now on (I need my disk space).

Subject: AT Dir Delay
I have just read a few items in Volume 5, Issue 98 concerning
"AT Dir Delay", and find them to be inconsistent with my experience.
All posters in that issue believe that the faster DIRs, or more
accurately, the faster free space calls, are due to the BUFFERS=nn
statement in one's config.sys file being high enough to hold one's
entire FAT in RAM.
My theory, (stress on theory) is that DOS 3.1 improved the free
space call to read the entire FAT once, and on subsequent calls,
rely upon the previous amount of free space found, modified whenever
any space is released or attached.
The empirical evidence I'm using here comes from my experience
with a 32mb disk under PCDOS 3.0, which paused after each free space
call, regardless of the number of BUFFERS. I subsequently patched
DIR to not make the call, since I didn't give a bleep whether I had
2 or 5 mb free. I then installed 3.1, and noticed its current,
civilized behavior. And smile each time it happens. %-)
Btw, CHKDSK does flush all buffers, and seems to also clear the
free space counter. (Ask Billy Gates why.)

I have used this program and it is often the "only" sane way to find

program is also a great tool for dissecting the operation of MS-DOS

Actually, the buffers command sets disk i/o buffers, not cache
buffers. The default is not 0! (how could you do any I/O with no
buffers?) In fact, the default is 2 (3 for AT's).
The advice about creating a CONFIF.SYS file is well taken. However,
buffers=20 is not absolutely the only good value. Good values are
said to lie between 20 and 30. I have yet to meet anyone who knew how
to pick a good value, though.
Yes, you should set FILES=20. You should also set BREAK to ON and you
will probably want to install the ANSI.SYS driver.
By the way, the article quoted above remarks that the CONFIG file must
be in the root directory. This is correct. There is an interesting
question: What other files must appear only in the root directory?
Many people believe that all these must appear in the root directory:
2 hidden files for DOS
AUTOEXEC.BAT
COMMAND.COM
CONFIG.SYS
Actually, COMMAND.COM does not! have to be in the root directory.
This is important if you a purist (as I am) who maintains that
the root directory should contain only other sub-directories
and as few files as possible.
I put all the DOS files (including COMMAND) into a DOS subdirectory,
which I reference with an appropriate PATH command in the AUTOEXEC.BAT
files. To boot properly, you need only include a SHELL command in
CONFIG.SYS. For example:
SHELL=\dos\command.com /p
You can use this same command to expand your environment (a must
for proper organization of a fixed disk). See your particular DOS
manual for details.
In order for programs to find COMMAND.COM when they need to, you
also need to set CONSPEC in AUTOEXEC.BAT. For example:
SET COMSPEC=\dos\command.com

No doubt that the copy that appears on that Florida BBS is stolen.
You can tell for sure by using a debugger to examine the beginning
of the load module for an IBM copyright.
If you are a beginner and you really want to know about how things work,
I suggest you try the DOS enhanced debugger (also IBM Personally

Also, try the snOOp (sic) program sold by Spite Software.
$49.95. snOOp disassembles anything and provides comments to make
it easy to take things apart and see how they work. Call 503-245-8102.
(I have no connection, by the way, with either IBM or Spite.)
Last, if you are a beginner and you are learning assembly language
