If you're not sure whether the motherboard BIOS supports PCI-to-PCI Bridges, ask the motherboard or computer manufacturer. The AHA-3940U supports up to seven 8-bit SCSI devices on each 8-bit SCSI channel.

PCI-to-UltraSCSI host adapters. These host adapters
have two SCSI channels which operate like
two
independent host adapters
. AHA-3940U/3940UW/
3940UWD host adapters are designed for computers
with PCI slots. PCI is a local bus interface that enables
high-speed data transfer.
The computer in which you
install the host adapter must be PCI 2.0 or
PCI 2.1-compliant, and the motherboard BIOS must sup-
port PCI-to-PCI Bridges (PPB)
. If you’re not sure
whether the motherboard BIOS supports PCI-to-PCI
Bridges, ask the motherboard or computer
manufacturer.
The AHA-3940U supports up to seven 8-bit SCSI
devices on each 8-bit SCSI channel. The
AHA-3940UW/3940UWD supports up to fifteen
16-bit or 8-bit SCSI devices on each 16-bit Wide SCSI
channel; up to seven of these can be 8-bit devices.
Installation procedures are the same for all three host
adapter models.
