Requirements For BIOS Tuning
Before we get down to the actual business, it is advisable to check whether or not the motherboard already has the latest BIOS version. To do this, the version shown in the bottom left-hand corner during boot-up should display the latest date. The best way to obtain the latest BIOS version is from the FTP server of the respective motherboard manufacturer.
On numerous motherboards, the BIOS is write-protected. This protection has to be disabled prior to burning, by jumpers on the motherboard, or in the BIOS itself.
