The flash memory of the server consists of a primary bank and a backup bank. You
must maintain a bootable UEFI firmware image in the backup bank. If the server
firmware in the primary bank becomes corrupted, you can either manually boot
the backup bank with the UEFI boot backup jumper (JP2), or in the case of image
corruption, this will occur automatically with the Automated Boot Recovery
function.
