BIOS-Update Howto - Step by step to a successful BIOS-Update

Never touch a running system!

This golden rule has its reason and says simply:
Don't update the BIOS when your PC is running smoothly!

Only when your BIOS has serious bugs, or newly built hardware such as CPU, RAM, hard drive, etc. is not detected, then a BIOS update should be considered. On the following pages you will find a step-by-step instruction how to update the BIOS.

 1. Preparation - Create a safe environment for a BIOS-Update
 2. Choose BIOS-Update method - DOS, Windows or per BIOS-Setup?
 3. Start the BIOS-Update - Flash your BIOS chip
 4. BIOS Update failed? - First aid

 

Attention: this Howto describes only a BIOS update according to standard, how it should work on most mainboards with AMI-BIOS, AWARD-BIOS or PHOENIX-BIOS. I cannot guarentee that it will work on your PC and I assume no liability for any damages! Please read the README files from your Mainboard manufacturer or PC manufacturer.

@Bill Meyer
quote from webpage: "This method simulates/emulates a floppy drive. Due to the size limitation of a 2.88MB floppy disk, you can only use a BIOS file and flashtool whose total file size is max ~2.7MB!"

Bill Meyer 15.Oct.2013 15:24

A warning on your webpage. Total size of your Dos and Bios files no greater than 2.77 Mb before burning to DVD/CD. I assume the data is corrupted? Can you explain in more detail.
