Managing and updating your BIOS
4. 1. 1 Using the computer system for the first time
It is recommended that you save a copy of the original motherboard BIOS along with a Flash Memory Writer utility (AFLASH. EXE) to a bootable floppy disk in case you need to reinstall the BIOS later. AFLASH. EXE is a Flash Memory Writer utility that updates the BIOS by uploading a new BIOS file to the programmable flash ROM on the motherboard. To determine the BIOS version of your motherboard, check the last four numbers of the code displayed on the upper left-hand corner of your screen during bootup. Type COPY D:\AFLASH\AFLASH. EXE A:\ (assuming D is your CD-ROM drive) to copy AFLASH. EXE to the boot disk you created.
AFLASH works only in DOS mode. It does not work in the DOS prompt within Windows, and does not work with certain memory drivers that may be loaded when you boot from the hard drive. Reboot the computer from the floppy disk.
BIOS setup must specify "Floppy" as the first item in the boot sequence.
4. In DOS mode, type A:\AFLASH <Enter> to run AFLASH.
If the word "unknown" appears after Flash Memory:, the memory chip is either not programmable or is not supported by the ACPI BIOS and therefore, cannot be programmed by the Flash Memory Writer utility.

4. 1. 2 Updating BIOS procedures
Update the BIOS only if you have problems with the motherboard and you are sure that the new BIOS revision will solve your problems. [. . . ] The PCI Bus Master can perform data transfer without local CPU help and furthermore, the CPU can be treated as one of the Bus Masters. PCI 2. 1 supports concurrent PCI operation to allow the local CPU and bus master to work simultaneously.
