BIOS Flash Utility

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.

NOTE: If you do not have a crisis recovery disk at hand, then you should create a Crisis Disk (See "Creating the Crisis Disk in Windows" on page 104)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.

Follow the steps below to run the Flash utility:

  1. Rename the BIOS file as "XXXXXXX.FD"
  2. Copy the "XXXXXXX.FD" file to a bootable USB device containing the Crisis Disk.
  3. Turn off the system power.
  4. Insert the USB device containing the renamed BIOS file and Crisis Disk to any USB port.
  5. Make sure the AC adapter is connected to a power outlet and plugged in to the system.
  6. Power on the system from an off state (i.e. cold boot) while holding down the Fn + ESC key.
  7. After POST, release Fn + ESC key. The system should boot from the USB device and perform crisis recovery action.
