The BIOS flash memory update is required for the following conditions:
•
New versions of system programs
•
New features or options
•
Restore a BIOS when it becomes corrupted.
Use the Flash utility to update the system BIOS Flash ROM.

Crisis Recovery
Diskette
before you use the Flash utility.
NOTE:
Do not install memory-related drivers (XMS, EMS, DPMI) when you use the Flash.
NOTE:
Please use the AC adaptor power supply when you run the Flash utility. If the battery pack does not
contain enough power to finish BIOS Flash, you may not boot the system because the BIOS is not
completely loaded.

Then boot the system from the bootable diskette. The Flash utility has auto-execution function.
