BIOS Recovery
An interruption during a BIOS flash procedure (e.g. a power outage) can corrupt the BIOS firmware, which will
cause the system to become unbootable. You need to access and execute the the boot block program to
reboot the computer and recover the regular BIOS firmware.
Observe the following when performing a BIOS recovery:
•
Make sure the battery pack is installed to the system and that the system is connected to a UPS
unit during the BIOS recovery and BIOS flash procedures.
•
The Crisis Disk should be prepared in a system running the Windows XP or Windows Vista OS.

Note that all data on the USB storage device will be cleared during the creation of the Crisis disk.

an available USB port.
