Appendix D – How to Upgrade a New BIOS
Please contact the Xycom Automation Application Engineering Department at 734-
429-4971 to obtain the latest BIOS.
BIOS Update Procedure
Notes
A. This procedure will erase any prior data on that floppy, so please proceed
accordingly.
B. Typically four files will be transferred, only COMMAND.COM being visible
when running a simple directory listing.
C. Please leave the diskette un-write protected for the balance of this
procedure.
1. Make a boot disk. Go to the DOS command prompt in MS-DOS or Windows 9x
and, with an available floppy disk in "A", type "format A:/s" That will format the
floppy and transfer the needed system files to it.
2. Download the BIOS upgrade file and awdflash.exe utility from an ICP web site
to a temporary directory on your hard drive, or directly to the floppy formatted in
step 1.
3. Copy (BIOS file and awdflash.exe) files to the boot floppy disk.
4. Reboot the system to the DOS command prompt using the boot disk made in the
previous steps.
5. At the DOS command prompt, awdflash filename.xxx, (filename.xxx is the file
name of the upgraded BIOS file), press Enter.
6. The first prompted option is to save the old BIOS. It is recommended that this
option be selected in case it is later decided not to use the new version once it is
installed. To save, enter Y. To not save, enter N.
Notes
A. DO NOT save the old BIOS with the same file name as the new BIOS. If
the same file name is used, the new BIOS will write over the old BIOS with
no prompted warning.
B. If the old BIOS is not saved write down the version number of the old BIOS
and store it with your important computer documents. If not saving old
BIOS, enter N (for "no") and skip to step 9.
