VLB SCSI?

I'm sure that ADAPTEC must currently produce SOME products that work. I gave up
on them and their putative warranty some 5-6 years ago, before the current
popularity of WIDE SCSI hardware came about, hence have WIDE hardware from SIIG,
MYLEX, IBM, but not from ADAPTEC.

I don't know what's making these 2940/3940 boards break, but I think there's
some oddity in the way in which they handle the plug-n-play operation. Several
of them aren't found by the system at all, i.e the ROM isn't even seen by the
motherboard, and, in those cases, the hardware doesn't appear under the OS,
either. Others find the ROM, but don't seem to operate the SCSI channel. Still
another (several) work in the old slow motherboards but not in the ones that
operate at a clock of 66 MHz or faster.

By contrast, the very first ADAPTEC cards I got, e.g. AHA1542, AHA1520, AHA1522,
AHA2842, etc, all seem to work just fine.
