This appears to be the motherboard click here and this appears to be the latest BIOS click here is this the board you have and is this the BIOS flash you are trying. If so then the only thing I can think is the download you have is corrupt and try downloading it again.
Absolutely right on all counts, I have downloaded and re-downloaded, is there such a word? I have also downloaded with and without Getright (download accelerator/manager) and I still get the same result.
That is indeed the same form I used to send my query to without any success.
