Is it possible: PCI+IDE+(Adaptec 1542b + SCSI)?

Post by Yanming PE » Tue, 27 Jun 1995 04:00:00



The Pentium has on-motherboard PCI IDE adapter but no SCSI
adapter available. Is it possible to use a Adaptec 1542b
ISA SCSI adapter on it to access SCSI devices? Or I have use
PCI SCSI adapter to access SCSI devices?

I have read the SCSI howto and have not found the answer to
the question. Any information will be appreciated.

It's possible to use an ISA SCSI adaptor but the performance will be better
with the vastly greater bandwidth of PCI. Of course if you already have the
1542B then it's probably not worth junking it in favour of a PCI equivalent as
the performance on this is pretty decent unless you hang a whole load of
devices on.

1. Possible help on SCSI problem with Adaptec 1542B?

Hi, I'm having a problem with my AHA 1542B.  Because I modified my BIOS
so it uses address 334h instead of 330h (default), so that my MIDI card
can use the standard 330h for address.

When I use bootimage 0.98, it can't find any scsi hosts/drives/cd-rom.

Any help would be appreciated.
