Installing Your Controller

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

2

O BIOS ROM

enabled for PCI assignment. This ROM BIOS intercepts and processes Int13 BIOS

calls with an embedded DOS driver.

The Adaptec I

2

O BIOS ROM can be disabled or the address changed automatically

by the system’s Plug-and-Play BIOS. In systems with multiple controllers, the first

I

2

O controller found during boot loads its BIOS and installs all of the Adaptec

hardware on the system.

Any additional Adaptec I

2

O controllers that are found automatically detect the

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

2

O BIOS interrupt level (IRQ) and memory location for all

Adaptec PCI controllers in the system.

If problems occur, refer to Appendix C, “Troubleshooting,” for additional help.
