3.4.6 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 feature 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 alternative device.
Follow these steps to select a boot disk.
1. In the SAS3 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 shown in the following figure.
Figure 7 Boot Device on SAS Topology Window
If a device is currently designated as the alternative boot device, the Device Info column shows the word Alt.
3. To select the preferred boot disk, move the cursor to the disk, and press Alt + B.
4. To remove the boot designator, move the cursor to the current boot disk, and press Alt + B.
This controller no longer has a disk designated as boot.
5. To change the boot disk, move the cursor to the new boot disk, and press Alt + B.
The Boot designator moves to this disk.
6. To select an alternative boot disk, move the cursor to the disk, and press Alt + A.
NOTE To change the alternative boot device from one disk to another, follow step 4 and step 5 in this
procedure, but press Alt + A instead of Alt + B.
