3.2 Boot Option Priorities
3.2.1 Boot Option #1..2
These functions are used to form the boot order and are dynamically generated. They repre-
sent either a legacy BBS (BIOS Boot Specification) class of devices or a native EFI boot entry.
Press Return on each option to select the BBS class / EFI boot entry desired.
3.2.2 Hard Drive/Network Device/CD/DVD ROM Drive/Floppy Drive/ BEV
Device BBS Priorities
These functions lead to sub-menus that allow configuring the boot order for a specific device
class. These options are visible only if at least one device for this class is present. These func-
tions are dynamically generated.
The PXE boot devices (network adapters) are controlled via the kboardconfig uEFI Shell com-
mand. The PXE boot devices are listed as boot devices after being enabled by the uEFI Shell.
3.2.3 Add New Boot Option
This function is used to create a native uEFI boot option and is visible only if at least one ap-
propriate native boot device is present. Please refer to the documentation for the respective
native uEFI-aware operating system for further information about creating a boot option.
3.2.4 Delete Boot Option
This function is used to delete a native uEFI boot option. Please refer to the documentation for
the respective native uEFI-aware operating system for further information about deleting a boot
option.
Note: Do not delete the “Built-in EFI Shell” boot option as this would remove the uEFI
Shell from the boot order. In case the uEFI Shell got removed, use “Save & Exit” /
“Boot Override” / “Built-in EFI Shell” to recover.
