BIOS Update Procedure
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 ur to save, verify and update the system BIOS. A hard drive or a network drive can also be ud 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 the boards. If your motherboard does not have a Flash BIOS (EEPROM) you will need to u an EPROM programmer to re-program the BIOS chip. See your dealer for more information about this.

For example:

旻rom the Flash Memory Writer menu, lect "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 lect "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.

Once the BIOS has been successfully loaded, remove the floppy disk and reboot the s
ystem. If you write to BIOS but cannot complete the procedure, do not switch off, becau the computer will not be able to boo, and you will not be given another chance to flash. In this ca 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 tup. 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 ret 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 reflash it if you need to. (This option is not available when flashing an AMI BIOS).
2. If you have problems installing your new BIOS plea 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 cau for getting a "Memory Insufficient" error message when attempting to flash a BIOS.
If you have not ud a bootable floppy, insure a clean boot either by
