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.
