I have an old EISA motherboard with a 486DX/2 chip and 32 megs RAM (30pin-60NS) and all SCSI-2. The computer started acting up about three months ago in Linux with SCSI timeouts. I bought a new controller card for the SCSI-2 stuff and it never resolved (same card as the computer came with and identical settings). Then Windows '95 starting locking up all the time, and after about fifteen resets it would work ok until you turned it back off. Most of these lockups were due to GPF's. I formatted the drive and went back to WFW311 and now I have wierd errors like COMMAND.COM not present and it locks up, or numerous GPF's, Dynalinks not found, EMM386 not loading due to memory exceptions, etc. Could this be a bad addressing chip or something on the motherboard, and where can I get a shareware burn-in program to test the thing to be sure?
