The boot list can be changed in any of the following ways:
Change the order in BIOS setup utility.
Reorder the categories using the IPMI bootflags that the SP offers to the compatible BIOS during POST. The default priority order for categories is CD/DVD, disk, removable, and network. See Configuring Boot Order Using ipmitool .
Change the boot order using biosconfig. This manipulates the contents of CMOS and the BIOS boot block structures stored in NVRAM, which is a dedicated part of the BIOS ROM.
This chapter contains instructions for changing the boot order using biosconfig.
