Updating Your Motherboard's Bios - Asus KN97 User Manual

IV. BIOS SOFTWARE
Managing & Updating your Motherboard's BIOS
About the BIOS files:
When purchasing the ASUS KN97 motherboard, the BIOS image file (xxxxi.xxx) is
pre-programmed for the Pentium II processor. Another BIOS image file (xxxxip.xxx)
will be provided on the support disk for use with the Pentium Pro processor when
the C-P6S1 SEC card is purchased. Make sure that the correct BIOS is installed for
your motherboard and processor configuration or else your system may be unstable.
Updating BIOS (only when necessary):
1. Download an updated BIOS file from the Internet (WWW or FTP) or BBS, and save
it to the disk you created earlier. See ASUS Contact Information on page 3 for details.
2. Turn off your computer, open the system cabinet, and set the Flash ROM Boot
Block Programming jumper of the baseboard to Program or Enabled.
3. Boot from the floppy disk you created earlier.
4. At the DOS prompt, type PFLASH <Enter>
5. Select option "2. Update BIOS Main Block From File" from the Main Menu (or
option "2. Update BIOS Including Boot Block and ESCD" from the Advanced
Features menu if prompted by option 2 of the Main Menu).
6. On the next screen displayed, type the complete filename and extension of the new
BIOS file, and press <Enter>. The utility then updates the BIOS file from disk.
WARNING! If you encounter problems while updating the new BIOS, do not turn
off the system because doing so may prevent your system from restarting. Instead,
repeat the process. If the problem persists, use the original BIOS file you saved to
the disk earlier. If the utility is unable to successfully update a complete BIOS file,
your system may not boot up. If this happens, your system will need service.
7. After successfully updating the new BIOS file, exit the utility. Turn off the sys-
tem, then set the Flash ROM Boot Block Programming jumper of the base-
board back to its default setting of Protect or Disabled.
8. Turn on your computer and hold down <Delete> to run the CMOS Setup Utility.
Select "Load Setup Defaults" to load the new BIOS, after which you may set
other items from the main menu.
