I am new to CNC zone as a member but have used the website for a long time to get good info! So my thanks goes out ahead of my question! My torq-cut 22 motherboard went bad (Keyboard interface) so I replaced it with a old working 486 dx2-66. Everything seamed to work fine but when the BMDC tries to load, it times out and the C:> prompt pops up. My guess is the ISA control card is not communicating with the BMDC and not allowing it to load. Since the Keyboard would not work with the old motherboard, I had no way to access the original bios to see how the IRQ's and the like were set. If anyone has any Ideas or has changed motherboards on these DX-32 controls please let me know. From what I have read any motherboard with enough ISA slots, up to pentium 133 is suppose to work? I have played in the bios with different configurations but I either get IRQ errors or on some settings no errors, dos loads, dx-32 starts, but the BMDC never loads. I'm stuck!
