Obviously, can only attempt to solve 0183 once I get into the BIOS itself. Supervisor Password is still there regardless of the number of times I remove the CMOS Battery, and completely discharge the board... Leading me to believe it is in fact dead.

I will order a replacement in the morning, and advise of any updates.

Cheers

0271: Check Date and Time settings.
0183: Bad CRC of Security Settings in EFI variable.

A photo is also attached....
