How to Update a BIOS From Bootup

If you want to update your computer's BIOS from the machine's bootup process, you're going to have to create something called a "BIOS Update Disk." This may sound complicated, but as long as you have access to a floppy disk or CD-ROM, it can be completed in a few minutes. A BIOS Update Disk is bootable, which means that once placed in your drive your computer will launch your BIOS update utility automatically during a boot or reboot.
