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.
Instructions
1. Unplug all power cables leading to your computer. Open the computer casing using a Phillips screwdriver.
2. Locate the three-pin BIOS Recovery Jumper Block. Refer to the manual that came with your motherboard, because the location of the BIOS Recovery Jumper Block differs from each motherboard model. Usually, you can find the BIOS Recovery Jumper Block near the CMOS battery.
3. Change the BIOS Recovery Jumper to recovery mode. Again, refer to the manual that came with your motherboard to complete this task. It involves removing the jumper from the jumper block and attaching it again as specified on the motherboard manual.
4. Close the computer casing using the Phillips screwdriver and attach all power cables leading to your computer. Insert the floppy disk that you used to flash the BIOS earlier and boot up your computer. Flashing the BIOS is automatic and you can determine whether the BIOS in your computer flashed successfully after the light on the floppy drive goes off. Some motherboard models will notify you when the upgrade process has completed.
5. Turn off your computer and open the computer casing again using the Phillips screwdriver. Make sure that your remove the power cables before doing so.
6. Change the BIOS Recovery Jumper to its original position. Close the computer casing using the Phillips screwdriver and boot your computer. It should start normally now.
