The first question we have to ask is: Why did you update the BIOS?
It is widely recommended that a BIOS only be updated when the
computer has a specific problem that the specific BIOS update is
specifically designed to fix. Is that the case here?
Second question: Did you back up the existing BIOS before you tried
to update it, or do you know that the update process automatically
backed up the existing BIOS for you?
