    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...

    Windows 3.1 w/ Intel Inboard 386/PC - VxD Issue

    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 ??? /cimonvg

    running 5x86 cpu in IBM 5150 with Inboard/386

    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...
