If you have disk drives attached to a SCSI controller

Determining the Booting Controller
Adaptec RAID controllers are shipped with a controller BIOS ROM
enabled for PCI assignment. This BIOS intercepts and processes
Int13 BIOS calls with an embedded DOS driver.
The controller BIOS ROM can be disabled or the address changed
automatically by the system’s Plug-and-Play BIOS. In systems with
multiple Adaptec controllers, the first Adaptec RAID controller
found during boot loads its BIOS and installs all of the other
Adaptec controllers. Any additional Adaptec RAID controllers that
are found automatically detect the presence of the first controller
and disable their BIOS. 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 system BIOS should
automatically configure the controller BIOS interrupt level (IRQ)
and memory location for all Adaptec PCI controllers in the system.
