How to Fix a Bad BIOS Flash
Flashing the BIOS (Basic Input/Output System) on a motherboard allows you to update the current BIOS software with an improved version. However, an interruption during the upgrade progress can lead to a corrupted BIOS. You cannot boot a computer that has a BIOS corrupted due to incorrect flashing. If this is the case, you must use the BIOS Recovery Jumper to repair the BIOS.
