BIOS Boot Order
5-2
5.2. BIOS Boot Order
The boot order defines the order of devices on which the BIOS searches to find a
bootable operating system for the partition. The default boot order is
1. Removable media, if a CD/DVD/floppy disk drive is present
2. Mass storage drive (that is, a local hard drive)
3. EFI
shell
You can view the boot order or select a path for the current boot attempt using the BIOS
setup Boot Manager option, as described in
5.6 Viewing and Temporarily Changing
BIOS Boot Order
.
You can modify the boot order using the BIOS setup Boot Maintenance Manager option,
as described in
5.7 Updating BIOS Boot Order
. Changes to the boot order using Boot
Maintenance Manager persist across boots of the partition if the configuration does not
change.
5.3. BIOS
Settings
The BIOS settings are optimized for server performance. You can make changes to suit
your processing needs, such as to specify
•
Memory usage (sequential, interleaved, or mirrored)
•
Assignment of processor cores (that is, enable or disable individual cores)
Refer to
8.10.2 Disabling Processor Cores using BIOS Interface
for the procedure for
disabling cores. If you need to disable a socket, use the remote console interface, as
shown in
8.10.1 Disabling Processor Sockets using remote console interface
.
•
I/O settings, descriptions, and the skip list
Note: The I/O skip list is a list of PCI devices that request I/O resources but do not
require the resources to function properly. Enabling this option can require special
operating system drivers.
Refer to
5.8 Configuring BIOS Settings
for more information about changing BIOS
settings.
Changes to BIOS settings persist across boots of the system if the system configuration
does not change. Certain events, such as the following, cause the settings to be reset to
the default values:
•
Upgrading BIOS firmware
•
Replacing the boot cell or hardware in the boot cell
Some events can cause the settings to appear to change in ways that are not obvious,
such as changing the designated boot cell.
