You can select a boot disk in the SAS Topology window. The next time you boot the computer, the firmware moves this disk to scan ID 0, making it the new boot disk. This makes it easier to set BIOS boot device options and to keep the boot device constant during device additions and removals. You can also select an alternative boot device.

Selecting a Boot Disk
You can select a boot disk in the SAS Topology window. The next time you boot the
computer, the firmware moves this disk to scan ID 0, making it the new boot disk. This
makes it easier to set BIOS boot device options and to keep the boot device constant
during device additions and removals. You can also select an alternative boot device. If
the BIOS cannot find the preferred boot device when it loads, it attempts to boot from
the alternate device.
Follow these steps to select a boot disk:
1.
In the SAS2 BIOS CU, select an adapter from the Adapter List.
2.
Select the
SAS Topology
option. If a device is currently designated as the boot
device, the Device Info column on the SAS Topology window lists the word
Boot
, as
the following figure shows.
