Asus has released a new bios (BIOS 1006 FINAL) for the Asus A7V mainboard. Thanks SeBA.

Update: Received the follow email from SeBA:

Just to tell that I and many other people are experiencing serious problems with the new 1006 Bios for the Asus A7V.
In my case the computer would hang on bios post not letting me enter setup or booting from any device. A hardware cmos-reset was necessary and the problem reappears if I set the ram to 133
MHz (having a 133 MHz DIMM).
Other people experience Bsod´s in Win2k, WinME not booting at all etc.
I personally recommend staying with 1005d.
