Note: Most of the tools listed below are flashers. A flasher is a program used to update the BIOS on your PC. To use it, you'll also need a BIOS data file (eg. the BIOS code itself) - specific for your motherboard/computer. A flasher comes in multiple flavours: you have DOS and Windows versions and flashers specific for a BIOS brand (AMI, Award, ...)
On Wim's BIOS you can find the bios update itself via your motherboard manufacturer.
UniFlash is a free flash utility, that can flash a BIOS image on many motherboards. Check the website to see which motherboard chipsets are supported.
With an Award BIOS Flasher (awdflash) you can flash an Award or Award/Phoenix BIOS from a DOS environment. We have collected a list of current and old Award Flashers on our Awdflash download section.
Old versions of the Award Flasher (eg. 5.00) should only be used with older Award BIOS Core versions (eg. 4.50, not 4.51 or 6.0). Newer versions generally add new commandline options and support for different brands of Flash chips.
In general, when you download a BIOS for your motherboard, the manufacturer will have included a matching Award Flasher version.
A Windows based Award WinFlash also exists to flash your BIOS from Windows.
With an Phoenix BIOS Flasher (phlash) you can flash a Phoenix BIOS from a Windows environment. We have collected a list of current and old Phoenix Flashers on our Phoenix flasher download section.
The Flasher utilities are copyrighted by their respective owners.
New versions of the flashers generally only add support for new Flash ROM chips.
