to “To ISA Legacy IRQs”. A similar workaround may apply to other motherboards

with problems supporting channel B.

Another possible workaround is noted on Adaptec’s Web site at

http://www.adaptec.com/support/faqs/aha394x.html.

To use the AHA-3940 or AHA-3940W adapters, the motherboard must have a

BIOS that supports the DEC PCI-to-PCI Bridge chip on the host bus adapter.

User-level programs have exhibited problems on some PCI systems with an

Adaptec AHA-2940x card, including the following motherboard models:

PCI motherboards with a 60-MHz Pentium chip, with PCI chipset numbers

S82433LX Z852 and S82434LX Z850. The part numbers of the Intel

motherboards are AA616393-007 and AA615988-009.

PCI motherboards with a 90-MHz Pentium chip, with PCI chipset numbers

S82433NX Z895, S82434NX Z895, and S82434NX Z896. The part number of the

Intel motherboard is 541286-005. (Some Gateway 2000 systems use this

motherboard.)

The AA-619772-002 motherboard with 82433LX Z852 and 82434LX Z882 chips

causes random memory inconsistencies. Return the motherboard to the vendor

for a replacement.

If problems with user-level programs occur, use the BIOS setup to turn off

write-back CPU caching (or all caching if there is no control over the caching

algorithm).

If the AHA-2940 SCSI adapter does not recognize the Quantum Empire 1080S HP

3323 SE or other SCSI disk drive, reduce the Synchronous Transfer rate on the

Adaptec controller to 8 Mbps.

The AHA-3940 has been certiﬁed by Adaptec to work on speciﬁc systems. Our

testing has shown that the Solaris operating environment works properly in some

of those systems and not in others. If you encounter problems running the Solaris

operating environment on an Adaptec-approved system with the AHA-3940,

contact your technical support provider.

Conﬁguration Procedure

Using the Adaptec conﬁguration utility:

Conﬁgure each SCSI device to have a unique SCSI ID, and on the adapter’s

Advanced Conﬁguration Options setup menu, set the Plug N Play SCAM Support

option to Disabled.

If there is more than one controller (or an embedded controller), try to use one

IRQ per controller.

Enable bus mastering for the slots with your host bus adapters, when the choice is

given.
