6. Connect any external cables to the controller.
IMPORTANT: If you have disk drives attached to a SCSI controller with a Symbios chipset,
use SMOR to set the Bootable Devices option to Disable.
Determining the Booting Controller
Adaptec SCSI RAID controllers are shipped with an Adaptec I
enabled for PCI assignment. This ROM BIOS intercepts and processes Int13 BIOS
calls with an embedded DOS driver.
The Adaptec I
by the system's Plug-and-Play BIOS. In systems with multiple controllers, the first
I O controller found during boot loads its BIOS and installs all of the Adaptec

hardware on the system.
Any additional Adaptec I
presence of the first controller and disable their BIOS code. The disk controller that
has the lowest BIOS ROM address (typically, the lowest PCI slot number) will
become the booting controller.
Ensure that the Adaptec ROM occupies the lowest address if you want the Adaptec
controller to be the booting controller in a system with controllers from multiple
manufacturers.
Some system BIOS manufacturers select the smallest add-in BIOS as the first
candidate, therefore slot selection has no effect on which adapter BIOS loads first. In
this case, you need to disable the BIOS on selected adapters to control which adapter
is the boot controller. This procedure can also be helpful in situations where it is
physically difficult to manage the slot order.
Controller IRQ and Address
During the host system boot process, the host system BIOS should automatically
configure the Adaptec I
Adaptec PCI controllers in the system.
