Subject: ANN's & Image Proc on a 486...
Keywords: Weitek support, 8-bit grey level display

PC hardware has finally come of age enuf that i can buy a machine which
costs less than a car which will have throughput competitive with a
(shared) supermini.  So i'm gonna junk the old xt and buy a 25 MHz 486
machine loaded w/memory etc.  I intend to run Windows, if it doesn't
limit me in some way.  I intend to do image processing on 8-bit imagery
using Neural Net algorithms (i.e., lots 'o' flops - correlations, array
operations, statistical analysis) and i will need the CPU throughput
and 256-grey-level display capability to support it.

Since i have been out of touch with the PC world, i would like to
solicit some advice:

* I would like to get a Weitek coprocessor, but i would also like to
stay with Turbo C++ (i understand 2.0 does windows - any bugs?).  Can
the new Tc++ gen- erate Weitek code or is there some other compiler
compatible w/ Tc++ with which i can build a linkable library?

* I need to display 8-bit (256-level) grey scale with a minimum of
512x640 resolution (and square pixels!).  I have been told that there
is an enhanced VGA mode which supports this.  Which compilers and
graphics cards are able to work in this mode, if any?  I would like to
stay as "mainstream" as possible, e.g. paradise card, turbo c.

* I will eventually need to build a user interface and would prefer to
make it portable.  Thus i'd like to hear reccommendations/experiences
concerning X-windows packages running under MS windows.  Any comments
on mouse support would also be helpful.

I think that there must be other NN/IP researchers like myself who
would find this info valuable.  Please respond to this by e-mail and i
will summarize on the appropriate topics.  this is especially important
since i will be posting this to several PC HW, PC SW, and ANN topics
and might miss your response if you just posted it.  I will credit all
responses in my summary.

Thank you all in advance!

Subject: DMA & OS/2

In reference to what machines OS/2 can and can't run on.

I am running OS/2 on a 10 MHz AT clone, running 0 wait states to on
board memory, and selectable 1, 2, 3 for expansion slot memory.  I
bought an Everex RAM10000 when I was considering OS/2, but ran it using
VDISK for a while, with 2MB on it, at 1 wait state, and didn't notice
any problems.

Then I got a copy of OS/2 1.0 (it was given to me free, so why would I
complain).  It would not boot.  It would get a GP fault during boot of
the floppy disk.  I thought about it for a while, tried it on a real AT
(it worked) and started going through the boot program using debug.
What I also noticed, but didn't yet understand, the address that it
would fault at was not always the same.

To make things faster, I wrote some debug output to my large virtual
disk.  At some point, I used FC to compare two files that were supposed
to be indentical.  It found differences.  The differences were not
always in the same place.

The RAM10000 board had passed its memory test program a number of
times.  No parity errors or anything.

But in these machines, the parity is checked on board.  THere is no
parity check on the bus.  If a board can't respond within the given
number of wait states, garbage is returned.  I believe this is a but in
the PC bus standard, but thats another problem.

Anyway, set the machine to 2 wait states, OS/2 boots, and everything is
fine.

Why the RAM10000 will not run at one wait state, I do not know.  Everex
didn't know either.  (The system board is also everex, so I thought
they should.  They also claim that the RAM10000 will run with no
additional wait states.  It would not run at 1 wait state at 8MHz.)

Well, If this helps anyone get OS/2 running, then I am glad.  If anyone
knows how to make RAM10000's run at 10MHz, I would like to know.

The interrupt vector 41h, stored at 0000:0104, holds a DWORD pointer to
the current table of BIOS params for drive 0.  BIOS sets that pointer
to the Nth entry in a table at startup, N being the CMOS drive type
number.

The little program that he provides does the trick on AT machines, but
on my good old XT the numlock-key and the numlock-light go
"out-of-sync": the light is still burning while the function of the
numlock-key is switched off. Does somebody know how to turn off the LED
also?

Windows will multitask.  Given that one has enough memory and at least
a 386 machine.  I have been able to download files using a comm program
while working on a word processing program.  Granted multitasking seems
to work better with Windows based applications rather than DOS based
programs.

Subject: reading 41st track of 360K floppies

The one thing that previous replies have not mentioned is the track
limit programmed into the floppy disk controller. There is a disk
parameter table pointed to by the INT 1EH vector; that table contains a
track limit (39, 40?) which needs to be altered. After you've done
that, issue the BIOS INT 13H call to reset the controller, so that it
re-reads the parameters.

If you don't do this, the controller will reject all requests for
tracks/sectors out of the range set in the original table.

Subject: Info-IBMPC Digest V91 #67

   I am trying to use an 80387 EMULATOR,(which enables me to run
programs using the 87 without really having one) under Windows, without
success. When I try to run it under Windows, I get the message "This
program has violated system integrity and was terminated. Close all
applications and reboot the system".

The emulator, which is a TSR, runs
fine under DOS and other file managers. I tried loading it before
Windows, but then programs like MATLAB did not recognize it. Trying to
load it under Windows gives the above message. On the other hand,
Windows applications, like EXCEL for Windows report *80387 PRESENT*.
Any suggestions?

Subject: port redirection

This is not really about copy protection, tho' it sure looks like it.
Read on!  I have two programs that require for running that a plug be
plugged in the printer port. With the printer itself, that makes a
daisychain of three elements.

Considering that (distance (computer-wall))<Sigma(3 elements) I am
looking for a way to convince either the security check or the real
printout stream to go to another parallel port (I have two) I could not
work it out with lptx.

Any clues?

Subject: Running Extra! and PC/TCP under DESQview

I seem to be experiencing problems with running both Attachmate Extra!
v1.41 and FTP Software PC/TCP under DESQview/386 v2.26.

I had previously run Extra! and ProComm Plus under DESQview without any
major problems.  However, on occasion when I'm doing an FTP in my
PC/TCP window it seems to "hang" up.  I still have control of my PC
(i.e., I can still invoke the DESQview menu and switch to other
applications), but the file transfer just stops.

I would be interested in seeing what kind of settings you have put in
your DVP files for Extra! and PC/TCP (whether or not you're running
both).  I am currently giving 9 ticks to the foreground task and 3
ticks to the background task.  I am willing to tinker with this, but
I'd be interested in hearing about any values that you have found to be
effective.

By the way, I'm (reluctantly) loading all of my Ethernet, LAN, and
TCP/IP drivers before I enter DESQview-- loading any or all of them
within DESQview seems to be a sure way to provoke a crash.  I'm kind of
on the "bleeding edge" here as farr as DESQview is concerned, so I'd
appreciate any hints you can offer.  Thanks!
