It had Phoenix Bios (Award) v. 3.0 but it is printed on motherboard "L7VMM2 v. 1.1".
I tried to flash the correct bios from ECS site running AWD822A Utility and after that the motherboard came dead.
I remove the the RAM and the board beep.
I tried to get a Checksum Error by shortcutting the 2-3 Bios pins and with this I was able to reflash it (yet with awd822a) but after reboot the board was still dead.
I shortcut again the 2-3 Bios pins and I was able again to bootblock this time running UNIFLASH Utility with the "-E" parameter.
After the 2nd beep I had the power supply interrupted, before the flash completely done.
Now I can't even shortcut the Bios pins. If I remove the RAM the board doesn't beep anymore.
Please, any help or advise will be welcome.
