Just in case it's helpful to know.. I've seen something very similar to this (variously "FPU unavailable" and a dump like the above, or "FP exception" with no dump) from CWSDPMI on a system with a known-buggy CPU (Intel P24T "Overdrive" which is an 83MHz 486DX. This CPU also caused OS/2 to commit seppuku with an "internal processing error at location [long address]".) What hardware do you need for testing, and what needs to be run to get a good test? I have these boards here that I could set up with some reasonable amt of memory (up to 16mb) if you've got something smallish that would work to test against 'em: 386SX16 w/ 387SX16 386SX40, no mathco 386DX40 w/ 33MHz mathco 386DX40, no mathco 486SX25, no mathco. Yes, I do have a weird collexion of old hardware :) ~REZ~
