If the BIOS code has become damaged, such as from a power failure
during a flash update, you can recover the BIOS code using the boot block
jumper and a BIOS flash diskette.
Note: The flash memory of your engine contains
a protected area that cannot be overwritten. The recovery boot block is a
section of code in this protected area that enables the engine to start up
and read a flash diskette. The flash utility recovers the system BIOS code
from the BIOS recovery files on the diskette.
