Bios Update Procedure
BIOS Update Procedure
(Page 1 of 2)
All latest Motherboards today, 486/ Pentium / Pentium Pro etc.,ensure
that upgrades are easily obtained by incorporating the system BIOS
in a FLASH Memory component. With FLASH BIOS, there is no need to
replace an EPROM component. Once downloaded, the upgrade utility fits
on a floppy disc allowing the user to save, verify and update the
system BIOS. A hard drive or a network drive can also be used to run
the newer upgrade utilities. However, memory managers can not be installed
while upgrading.
Most pre-Pentium motherboards do not have a Flash BIOS. The following
instructions therefore do not apply to these boards. If your motherboard
does not have a Flash BIOS (EEPROM) you will need to use an EPROM
programmer to re-program the BIOS chip. See your dealer for more information
about this.
Please read the following instructions in full before starting a Flash
BIOS upgrade:
A. Create a Bootable
Floppy (in DOS)
•With a non-formatted disk, type the following:
format a:/s
•If using a formatted disk, type:
sys a:
This procedure will ensure a clean boot when you are flashing the
new BIOS.
B. Download the BIOS
file
•Download the correct BIOS file by clicking on the file name
of the BIOS file you wish to download.
•Save the BIOS file and the Flash Utility file in the boot disk
you have created. Unzip the BIOS file and the flash utility file.
If you don't have an "unzip" utility, download the WinZip
for Windows 95 shareware/ evaluation copy for that one time use from
_www.winzip.com or _www.pkware.com. Most CD ROMs found in computer
magazines, have a shareware version of WinZip on them.
•You should have extracted two
files:
Flash BIOS utility eg: flash7265.exe (for example)
BIOS eg: 6152J900.bin (example)
Use the latest flash utility available unless otherwise specified
(either on the BIOS update page or in the archive file). This information
is usually provided.
C. Upgrade the System
BIOS
During boot up, write down the old BIOS version because you will need
to use it for the BIOS backup file name.
Place the bootable floppy disk containing the BIOS file and the Flash
Utility in drive a, and reboot the system in MS-DOS, preferably Version
6.22
•At the A:> prompt,
type the corresponding Flash BIOS utility and the BIOS file with its
extension.
For example:
flash625 615j900.bin
•From the Flash Memory Writer
menu, select "Y" to "Do you want to
save BIOS?" if you want to save (back up) your current BIOS (strongly
recommended), then type the name of your current BIOS and its extension
after FILE NAME TO SAVE: eg: a:\613J900.bin
Alternatively select "N" if you don't want to save your
current BIOS. Beware, though, that you won't be able to recover from
a possible failure.
•Select "Y" to "Are
you sure to program?" Continued
