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!

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. ------------------------------ Date: 25 Mar 91 16:23:42 MST From: Gary Dobbins <GARY@euphrates.ccit.arizona.edu> Subject: Where is Hard Disk Info Stored in CMOS (V91 #67) > Date: Mon, 18 Mar 91 11:28:39 EXP > From: Kim Jin Soo <WATER4%KRSNUCC1.BITNET@uga.cc.uga.edu> > In AMI Bios, When We setup the User HDD type, where goes this info? > First, I thought this info. might go into CMOS Ram.

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?

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.

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*.

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? David Leiser ------------------------------ Date: Mon, 25 Mar 91 18:55 CST From: Dave Ulrick 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!
