Flash (BIOS) Update Procedure
1. Prepare a bootable DOS diskette disk with AFLASH.EXE, MSG.DAT,
RXX-YY.RN and RXX-YY.BIN.
Note: The AFLASH.EXE and MSG.DAT are flash utility program. The
RXX-YY.RN file has the BIOS checksum information. The RXX-
YY.BIN is BIOS source code binary file and its file size should be
131.072 bytes.
2. Insert the diskette disk and boot up from Drive A:.
Warning: Do not boot up with any memory related driver such as
HIMEM.SYS, EMS.SYS ….
3. Run AFLASH.EXE
4. Press any key to pass the information screen, execute “LOAD BIOS FILE
TO BUFFER” and key-in BIOS file name (RXX-YY.BIN). Program then
automatically loads BIOS file into memory buffer. If the BIOS file does not
exist, a warning message will appear on screen.
5. Verify the checksum value is same to the information from RXX-YY.RN
file.
6. Execute “PROGRAM FLASH ROM” from main menu.
Warning: Shutting down the power, or resetting the system (or any
interruption) while the AFLASH program is programming BIOS will
result in the corruption of system BIOS. This will render the system
inoperative. In the event that this happen, the “bad” flash ROM will
have to be replaced with a successfully programmed BIOS. Please
see “Parts Catalog” on page 7-4 for a programmed BIOS FRU
number information.
7. Follow the instruction on screen to complete the programming BIOS.
8. Power off system after the BIOS is been completely updated.
