Hi there,
If you have F6 as your current BIOS you can flash the back-up BIOS chip to match in case you encounter any other problems.
To do this where you would normally press DEL to enter the BIOS, instead press Alt + F12, this will flash the Backup BIOS with the MAIN BIOS contents. Do not worry when you see a recovery comment, that is normal and means it is flashing the backup BIOS.
I find it is better if you can use a PS/2 keyboard to do this and also it may take several attempts before it works.
To check that both BIOS chips have the same version, press F9 when you are on the BIOS home Screen. Another window will open that gives you such information.
