I have the Adaptec 1542B running on a JDR 386 motherboard using this level
of Unix from Intel without a glitch, in fact I'm running both SCSI and IDE
drives in this system, unsupported according to the documentation from Intel,
for about 3 months.

I also know of a system using the WD-7000 FAST and also with IDE's again
no problems.
