009.01.16.5. BIOS updates are essential for system stability and hardware compatibility. What precautions should be taken when updating the BIOS, and why is it considered a sensitive operation?
BIOS update is a sensitive operation, and if, done improperly, can lead to system malfunctions. Updation should be done only when necessary for compatibility or performance improvements.
1)First, back up your data. An "almost working" BIOS that doesn't quite work with your hard drive can blow away your data. 2) Back up your current BIOS code, if you can. 3) Record your hard drive configuration information. 4) Record other nonstandard BIOS settings 5) Check to see whether your system has a write-protect setting jumper on the motherboard that must be adjusted to allow a BIOS update to take place.
