How to Remove BIOS Updateby Helen Jain
BIOS, or Basic Input/Output System, hardware is designed only to update when there are problems. Otherwise, it does not need updating. The BIOS updates are made for specific BIOS problems such as a bug in the system, but the problems are not associated with every version of BIOS. Sometimes, updating the BIOS will result in computer problems. When the computer has problems as a result of the BIOS update, removing the update can usually fix the problem.
Download a recovery BIOS. Removing the BIOS update requires completely restoring the BIOS to its original factory condition, which requires a recovery BIOS. Obtain the BIOS that the computer already uses that does not have the update.
Copy the recovery to a USB disk. This saves the recovery.
Plug the USB disk into the computer that has the BIOS system update.
Turn off the computer and unplug the adapter.
Remove the BIOS configuration jumper. The exact location differs for each computer. The configuration jumper is a small rectangular item that is yellow in color and located in the chassis.
Turn the power on and allow it to load. The recovery starts automatically. Wait until the recovery is complete. The computer will either turn off automatically or will give a prompt to turn it off. If it does not turn off automatically, turn it off when prompted.
Remove the USB drive and replace the BIOS configuration jumper. Close the chassis. Turn on the computer. The only way to remove an update is to recover the original BIOS settings.
Have a professional do the recovery if it seems complicated or the appropriate BIOS is unclear.
