Create a safe environment for a BIOS-Update
It is very important to create a safe environment before starting a BIOS update.
- Identify the installed BIOS version:
The version number and date of the installed BIOS version can be identified relatively easily. If you're not sure, then take a look in the download section on the manufacturers website of your Brand PC, Notebook or Motherboard, to find the BIOS version and BIOS date:
Tip: press the PAUSE key to stop the scrolling boot screen.
- Identify the mainboard manufacturer, type and version:
This is most often only required if you have bought the mainboard in its original box:
On a Brand PC or Notebook you will need instead the model name and serial number, which you can most often find on a sticker on the PC case.
- Download the BIOS-Update files
From which location do i get the BIOS-Update file and flashtool?
- If you have bought the mainboard in its original box: mainboard manufacturer website.
- If you have a notebook or brand PC: notebook/brand PC manufacturer website.
This is a very important decision, because your PC will not work with a wrong BIOS version!
Watch out for so-called OEM-Mainboards !
- Rename BIOS-Update files: if you intend to update your BIOS with a bootable USB-Stick/Diskette/CD under DOS, you have to rename the BIOS file and flashtool filename (not the filename extension!) when the filename has more than 8 characters! Reason: see 8.3
- Create a Backup: if your manufacturer does not have your current BIOS version on his website. Use the backup function of your flash software, if you are using a rewriteable medium like USB-Stick, Diskette, or Hard disk (with FAT16/FAT32 partition).
- Save current settings: write down or take a picture from your current BIOS-Setup settings if you have changed the default settings, because you will lost these settings during the BIOS update.
- Load default settings: make sure that your PC is not overclocked and disable all tuning settings. Load the default BIOS-Setup settings, called: "Load Bios Defaults" , "Load Setup Defaults" , or "Safe Settings".
- Remove write protection: some mainboards have jumpers to protect before erroneously flashing the BIOS. The jumper position is most often nearby the BIOS-Chip. There should be a layout plan in your mainboard manual, which shows the position of your Bios-Chip and the jumper. Other mainboards have a BIOS-Setup option called "Flash Bios Protection", "Firmware Write Protect", "Bios Guardian" or "BIOS-ROM Flash-Protect", which must be disabled.
- Stop Anti virus scanner, etc.: close all programs (Email clients, AV scanner, Firewalls, Office programs, etc.) which could disrupt Windows or the flash program.

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.
