BIOS Updates forum

ASUS recommends keeping a copy of the original BIOS. How do I record the original BIOS from my motherboard?

If it is an Award BIOS, create a boot diskette with no autoexec.bat or config.sys. Copy the Award flash program (e.g. awdflash.exe), bott from the diskette and use the command line:
awdflash savebios.bin /sy/pn
where awdflash.exe is the name of the Award flasher.
That's an example. For other flash utilities similar options exist.

Asus uses AFLASH as flashprog for Asus-Award Bios and it has the option to save a copy of your old Bios before updating the new one

The Liveupdate utility may have this option,too
