Updating a Asus BIOS ?

Hi,

my BIOS crashed recently so i forced to copy a similar BIOS from a front using a BIOS flasher.

my Asus motherboard is p4p800vm and the current loaded bios is of p4p800mx this is some what compatible with the board, but not fully supporting it.

I tried to flash bios using Asus bios update utility (am having a fresh copy of my old bios (p4p800vm.rom)) but it is not allowing to flash the bios, saying its not the correct bios. Is ther any way to get rid of this problem? If anybody know a solution to update my bios with a bios rom file which is different from the current bios. Pls help

i tried updating it with afuwin utility two times, both way it passed although the flashing but not booted up the system afterwards. Is thr any specific way to use afuwin on Asus p4p800vm motherboard, if available may solve my problem.


thanx in advance
