In running a 486DX-50 on Now that y'all mention it: on the pentium at work, FreeBSD worked fine when running just a scsi disk. After I added an IDE drive, it started crashing after a short while, occasionally corrupted the disks (both of them), etc. Turns out that the wait states and clock speed for one of the busses was a little optimistic (PCA or ISA - I don't know or care which, I just decreased them both). Note that the combination had worked fine under dos; perhaps dos (or my dos scsi driver) doesn't stress bus speeds :) Food for thought, anyway.
