Configuring the BIOS

Your system BIOS may determine available NIC resources and
configure the Adaptec PCI NICs automatically. However,
depending on your system, you may need to configure the PCI
BIOS. To do this, enter your computer BIOS Setup and select
Advanced Settings from the Main Menu. Make sure the following
settings a re made (your BIOS may not match the following options
exactly):
Two-and-four port NICs use a PCI-to-PCI bridge chip. If your
system’s BIOS does not support the PCI-to-PCI bridge chip these
NICs will not be configured properly. Contact your comp uter
manufacturer to obtain a new BIOS version th at supports the PCI-to-
PCI bridge chip.
