1. Replacing the ROM chip with a new chip containing the update software (the most complicated one for the regular user, so we won’t cover this option).

2. Upgrading the BIOS using a program embedded on your motherboard (easiest and thus preferred way). Not all motherboards provide this option.--> Page 1 and 2

3. Upgrading the BIOS using a Windows-based programmer.--> AWARD and AMI

4. Upgrading the BIOS using a DOS-based programmer.--> Guide Here

If you use the wrong BIOS file or if power runs out during the BIOS upgrade the worst thing that can happen is your PC not turning on anymore – all you will see is a blank screen.

Luckily newer versions of BIOS upgrade programs check if the BIOS you are trying to upgrade was written for your motherboard, so the chances you program the wrong file are very small.

But if you turn off your PC during the BIOS upgrade process – whether this was done on purpose or by accident –, you will probably corrupt the BIOS chip, “killing” your motherboard. It won’t turn on anymore.
