hello
Application is mentioned " Test your system using SXCHK.EXE if it yours is compatible with this upgrade." here : 386 CPU Upgrade
perhaps it can tell if your system will work with 486sx..

hello
Just remember one case. Where I pimped 486BL and then warm rebooted. The inboard driver complanied about bad RAM, but in that case , it was too fast "pimping" of CPU (enabled CPU-cache prior to load of Inboard driver), then testing RAM and failing...

hello
i don't know how Stynx did manage to enable keyboard in Doom, My demo ran automatically and then gave framerate numbers.
But perhaps Doom runs better on IBM5160 then the IBM5150?
Otherwise you should be able to run the game with mouse and joystick (i think - have not tried) on the IBM5150...
i did use the packet described on first page :
"I did use the speed test from
http://www.philscomputerlab.com/dos-benchmark-pack.html"
..it gives you a number you calculate to a fps.

Hello
My hobby has for some years been the IBM5150 - and i have used many hours on the IBM5150 and Inboard386, but only now started with the IBM5160 and Inboard386, so here also new stuff for me.
The other thread "Windows 3.1 w/ Intel Inboard 386/PC - VxD Issue" harrision.frazier mentioned a...
hello
one more run
well same vga,hd,floppy but now in IBM5160 and it works! I did copy the Harrison.frazier WINDOWS library to my SCSI disc. And my IBM5160 XT now runs windows with DOS box ;)
My IBM XT is a 64-256k "6181696" system board.
Did also a Windows95 test - but no go..
Thanks harrison...
only got a few comments.
One i had some issues with a CPU not plugged 100% into the socket. When pussing the CPU way down , it started again..
And the fingers on the ISA part of the Inboard386 , mine gets "black" in no time. Ones in a while i pollish the fingers with alcohol and a cotten-bud...
hello - my first attempt , did not work.
Took your windows directory onto my SCSI-drive. (my os is still PCDOS 7.0) Probably hardware differences, i can not boot without device=ibvpicd.386.
Perhaps later IBM pc xt are easier getting to run accelerated software ? then the older pc 5150 ???

hello
exciting - hope you will share your setup settings.
Either or both a software / hardware settings may be wrong in my setup - i do also get error "device number 0003, service 0013".
Software:
What is the config.sys file containing ?
- the Netroom software is nice and perhaps it can fix all...
hello
i do use Transcomputer interposter (if you look 2 pages prior this page).
There is uploaded a "jumper settings" sheet on "https://forum.vcfed.org/index.php?threads/running-486-on-inboard-386.47554/page-2" , but that is another interposter board.
And a VRM, due to the CPU do not like...
hello
Watch out for the frequency, the CPU can handle alot more then the Inboard386. I do run 20Mhz (40Mhz crystal) on my inboard386 and with the x4 setting on the Cyrix5x86 it runs like 80 Mhz - and i have not seen any errors due this frequency (yet). You never know if errors will appear, now...
hello
I don't know if I'm the expert - but, I've definitely spent a lot of time on this accelerator hobby.
I know more about electronics and less about software, hoping some more software-knowledgeable person can figure out this 0Kb issue.
But if you look at my post about...
hello
my inboard's have also been reporting 0Kb in DOS.
But you can test the memory with Checkit version 4, many other memory test applications do not recognize any memory.

hello
not every week you see BOTH Inboard386 and the appropriate Windows version NIB
