I don't know whether this is applicable to your particular board (the one I'm contemplating buying) but on the CD received with my A7V266E board there was the following:
-Readme.txt -Information on how to use the AFlash BIOS utility V1.37.
-Aflash.exe -Utility to update the motherboard's flash BIOS.
(This was in the "Software" folder)
Hope this helps.
