ATCA-7350 Control via IPMI Programmer’s Reference (6806800H29E)

Supported Commands Chassis Device Commands

2.1.7 Chassis Device Commands

2.1.7.1 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.
