Bios Update Procedure
BIOS Update Procedure
(Page 2 of 2)
•Wait until it displays "Message: Power Off or Reset the
system"
Once the BIOS have been successfully loaded, remove the floppy disk
and reboot the system. If you write to BIOS but cannot complete the
procedure, do not switch off, because the computer will not be able
to boo, and you will not be given another chance to flash. In this
case leave your system on until you resolve the problem (flashing
BIOS with old file is a possible solution, provided you've made a
backup before)
Make sure the new BIOS version has been loaded properly by taking
note of the BIOS identifier as the system is rebooting.
For AMI BIOS
Once the BIOS has been successfully loaded, remove the floppy disk
and reboot the system holding the "END" key prior to power
on until you enter CMOS setup. If you do not do this the first time
booting up after upgrading the BIOS, the system will hang.
BIOS Update Tips
NOTE:
1. Make sure never to
turn off or reset your computer during the flash process. This will
corrupt the BIOS data. We also recommend that you make a copy of your
current BIOS on the bootable floppy so you can re flash it if you
need to. (This option is not available when flashing an AMI BIOS).
2. If you have problems
installing your new BIOS please check the following:
Have you done a clean boot?
In other words, did you follow the above procedure for making a bootable
floppy? This ensures that when booting from "A" there are
no device drivers on the diskette. Failing to do a clean boot is the
most common cause for getting a "Memory Insufficient" error
message when attempting to flash a BIOS.
If you have not used a bootable floppy, insure a clean boot either
by
a) Pressing F5 during boot up
b) by removing all device drivers on the CONFIG.SYS
including the HIMEM.SYS. Do this by using the EDIT command.
Have you booted up under DOS?
Booting in Windows is another common cause for getting a "Memory
Insufficient" error message when attempting to flash a BIOS.
Make sure to boot up to DOS with a minimum set of drivers. Important:
Booting in DOS does not mean selecting "Restart computer in MS-DOS
Mode" from Windows98/95 shutdown menu or going to Prompt mode
in Windows NT, but rather following the above procedure (format a:
/s and rebooting from a:\).
Have you entered the full file name of the flash utility and the BIOS
plus its extension?
Do not forget that often you will need
to add a drive letter (a:\) before flashing the BIOS.
Example: when asked for file name of new BIOS file which is
on your floppy disk, in case you're working from c:\ you will need
to type a:\615j900.bin, rather than 615j900.bin only.
