I managed to download and install @BIOS with no problems.
I ran it and hit the "Update BIOS from GIGABYTE Server" button.
Please select @BIOS server site:
server 1 in Taiwan
server 2 in Taiwan
server in China
server in Japan
server in U.S.A.
I selected U.S.A. the first time I tried, this time I selected server 1 in Taiwan.
It then asked me to select a file to update and showed me the following:
Model Name: GA-7VM400M (2.0)
VIA KM400, AWARD BIOS, Ver.FD
This seems to be correct so I select that and hit OK.
The progress bar goes across to 100% and it says:
The screen will freeze for a few seconds while updating the BIOS.
Do you want to update the BIOS?
I hit OK.
It does some loading/erasing, then the screen goes blank and displays the following:
Once that's done, it reboots to display:
This shows that there was an error and the BIOS did not update.
I've tried @BIOS twice now, both forced the system to reboot.
Where do I go from here?
