Corrupt BIOS

[Superpatsy]

Apologies if this is in the wrong section.

Turned on my PC last night and was met with the fantastic message that my main BIOS was corrupt and that it was being recovered from the backup BIOS.

My question is, how does this work? Does the backup BIOS become the main and the corrupt one is left as the backup or does the backup become the main, and then become the backup? If that makes any sense...

Cheers!

As far as I know the backup BIOS, overwrites the corrupt one.

Once it is over written the system continues to use BIOS chip one (The one which was corrupt before)

After saw Dual BIOS video. When main BIOS corrupted then main BIOS will be recovered and updated from backup BIOS.
