Except Asus:

Not really a flash program but functions to enable / disable write
protection of the bios chips and address spaces. There's an AWDFLASH
structure that points into this. I reverse engineered this many years
ago until I found out that I want to support hardware that is supported
by its vendor.

Thats definitely not what the user land bios flashers like uniflash use.
it seems they want to get rid of bios updates while the os is running
completely. Not dumb, really.
