Appendix C:Updating the FLASH ROM BIOS
BIOS Version
Make sure you download the latest correct
version of the BIOS appropriate for the computer model you are
working on.
You should only
download BIOS versions that are
V1.01.XX or higher as
appropriate for your
computer model.
Note that BIOS versions
are not backward compatible and therefore
you may not downgrade your BIOS to an
older version after up-
grading to a later version (e.g if you upgrade
a BIOS to ver 1.01.05,
you MAY NOT then go
back and flash the BIOS
to ver 1.01.04).
To update the FLASH ROM BIOS, you must:
• Download the BIOS update from the web site.
• Unzip the files onto a bootable CD/DVD/USB Flash Drive.
• Reboot your computer from an external CD/DVD/USB Flash Drive.
• Use the flash tools to update the flash BIOS using the commands indicated below.
• Restart the computer booting from the HDD and press F2 at startup enter the BIOS.
• Load setup defaults from the BIOS and save the default settings and exit the BIOS to restart the computer.
• After rebooting the computer you may restart the computer again and make any required changes to the default BIOS
settings.

2.Use your user ID and password to access the appropriate download area (BIOS), and download the latest BIOS files
(the BIOS file will be contained in a batch file that may be run directly once unzipped) for your computer model
(see sidebar for important information on BIOS versions).
Unzip the downloaded files to a bootable CD/DVD/ or USB Flash drive
1.Insert a bootable CD/DVD/USB flash drive into the CD/DVD drive/USB port of the computer containing the
downloaded files.
2.Use a tool such as Winzip or Winrar to unzip all the BIOS files and refresh tools to your bootable CD/DVD/USB
flash drive (you may need to create a bootable CD/DVD with the files using a 3rd party software).
Set the computer to boot from the external drive
1.With the bootable CD/DVD/USB flash drive containing the BIOS files in your CD/DVD drive/USB port, restart the
computer and press F2 (in most cases) to enter the BIOS.
2.Use the arrow keys to highlight the Boot menu.
3.Use the “+” and “-” keys to move boot devices up and down the priority order.
4.Make sure that the CD/DVD drive/USB flash drive is set first in the boot priority of the BIOS.
