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 BIOS 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 start process, the system BIOS should
automatically configure the controller BIOS interrupt level (IRQ)
and memory location for all Adaptec PCI controllers in the system.
