READ THIS FIRST!
Before you continue, make sure your system meets
the following minimum requirements. If it does not,
the AHA-398x will not work!
■ The motherboard chipset and system BIOS must
support
– PCI-to-PCI bridges
– A 64-KByte BIOS
– Multiple interrupts
– at least one full length PCI slot
To determine whether your motherboard pro-
vides this support, contact your vendor, or call
Adaptec’s Interactive Fax system for a list of com-
patible motherboards (the number is on page 12).
■ The computer must comply with PCI Rev. 2.0.
■ If you are running NetWare 3.11, the clib.nlm must
be version 3.12 or above. See the Troubleshooting
Checklist on page 10 for more information.
AHA-398x Overview
Each AHA-3980 and AHA-3980W has two SCSI chan-
nels: A and B. Each AHA-3985 and AHA-3985W has
three SCSI channels: A, B, and C.
The AHA-3980 and AHA-3985 are 8-bit adapters.
Each channel on these adapters supports up to seven
8-bit SCSI devices. The AHA-3980W and AHA-3985W
are 16-bit adapters. On these adapters, each channel
supports up to 15 SCSI devices. All 15 devices can be
16-bit, or you can combine 8-bit and 16-bit devices. If
you combine devices, a maximum of seven can be
8-bit devices.
AHA-398x adapters support SCSI devices running
under Novell NetWare 3.11, 3.12, and 4.x. They also
support most SCSI CD-ROM drives and hard disk
