System Boot Options Commands

The IPMI system boot options commands allow you to control the boot process of a blade by
sending boot parameters to the blade’s boot firmware (for example BIOS, U-Boot or VxWorks).
The boot firmware interprets the sent boot parameters and executes the boot process
accordingly. Each boot parameter addresses a particular functionality and consists of a
sequence of one or more bytes. The IPMI specification assigns numbers to boot parameters.
Boot parameters 0 to 7 are standard parameters whose structure and functionality is defined
by the IPMI specification. The boot parameters 96 to 127 are OEM-specific which can be used
for different purposes.

The following table lists which boot properties can be configured and the corresponding boot
parameter number.
