BIOS Crisis Recovery Mode
Immediately after a reset or power−up a routine in the boot flash boot block is invoked
which checks whether a valid BIOS image is available. If no valid image is found and
consequently the blade is unable to boot, the blade enters into BIOS crisis recovery mode.
In this mode a routine tries to load a BIOS crisis recovery image from a disk drive
connected to the blade’ s USB interface. The BIOS crisis recovery image is basically a mini
DOS with minimum functionality which replaces the corrupted image.

A valid BIOS crisis recovery image can be downloaded from the former Force Computers
SMART server or the Motorola website as part of the BIOS upgrade kit which which is
available for this blade. The image is accompanied by readme files which describe how to
create the BIOS upgrade/recovery disk and how to to replace a corrupted BIOS with the
BIOS crisis recovery image.

After the BIOS recovery image has been successfully flashed, the LED is lit green.

avoid blade damage, it is absolutely important not to interrupt the flashing process.
