17.1 Boot Device Selection

The Boot Options menu allows the user to modify the boot order by selecting the order of
various boot devices. Any boot order modifications can then be saved and remain persistent
across boot cycles.
The Boot Manager menu allows the user to override the current boot order and select a specific
device to boot the system.
Note: Any selection in the Boot Manager applies only to the current boot.
17.1.1

Server Managment Boot Device Control

The Intelligent Platform Management Interface Specification, Version 2.0, Intel Corporation
specification includes provisions for server management devices to set certain boot parameters
by setting boot flags. Among the boot flags (parameter #5 in the IPMI specification), the BIOS
checks data 1-3 for forced boot options.
The BIOS supports forced booting from the following media devices:
PXE
iSCSI
HDD (USB, SATA, and SAS)
USB FDD
USB Key Fob
DVD/CD-ROM
On each boot, BIOS invokes the Get System Boot Options command to determine what
changes to boot options have been set. The BIOS takes the appropriate action and clears these
settings.
17.1.2

USB Device Booting

USB boot devices can take on many different characteristics. The following rules are used in
detecting and booting from a USB device:
If the block size of the media is greater than 512 bytes then the emulation type is
assumed as CDROM (El Torito formatted).
If the device has a partition table with more than one partition then the emulation type is
assumed as "Hard Disk".
If the device has a partition table with only one partition then the device is emulated as
"Forced FDD".
All the other devices that do not follow the above rules are assumed as "Floppy Disk".
