The system I am running (or trying to run) sounds
like it has the same problem, as far as I can tell
the 1542 board I have (ISA, are they all ISA??) just
gives me grief.. I got it working in a 486dx2-66, but
sufferred numerous page missing page faults..
(Turns out most of these were my main system memory
was actually dead =( )

After sorting out the memory I completely lost the
page missing stuff for a while, but it's still there
any time I try to use /usr. (???)

I thought this might be a hardware conflict somewhere,
so I've changed every jumper setting/toggle switch on
the card and checked everything else. didn't help..

Eventually I stuck the card and scsi in another machine,
and as far as I can tell the 1542 card just wont work in
anything else now. (at least not on a pentium motherboard?)

This could mean I have a broken scsi card, but I think
more likely is that the aha driver doesn't support the
exact card I have.

My suggested solution (it's what I'm doing) is to buy a
Adaptec 2940 (or 3940 if you can afford it) instead.

Sorry I can't actually be of much help, but it might be
worth knowing that there is someone else who has had 
similar problems.

Good Luck Anyway:
	Steve.

P.S. I've tried EVERY BIOS configuration I can get to boot
and anything which boots just doesn't seem to work.. although
I could have missed something I suppose ?
