Award BIOS uses an in-flash structure starting with the magic
"AWDFLASH". It contains a couple of pointers to 16bit functions for
enabling/disabling shadowing and flash write protection.

AMI BIOS uses an intXX call for that. Refer to RBIL for more

So none of the dos tools knows about this itself. It just asks the bios
(image file) to show the system bios.

The sequence to call these in-flash enablers is well-known. Uniflash is
using them and so knows how to flash every board without the need for
new code, as long as it knows the flash chips.

I am not exactly convinced that this is legal. esreveR gnireenigne is,
in a couple of countries though
