Many users don't know the name of their clone motherboard. This is because the company name is not mentioned anywhere in the manual, or on the motherboard. If you want to upgrade your BIOS you really have to know the motherboard manufacturer, because if you flash the wrong BIOS upgrade your system could stop booting.

Luckily, Award and AMI BIOS have a unique BIOS ID (= BIOS Number) which identifies the manufacturer and chipset of the board. Phoenix BIOSs, in most cases, do NOT.

The AMI or Award BIOS id appears at the bottom of your screen after power on, during memory count up. The PAUSE key should work at that point, allowing you to write down the BIOS number, the BIOS date, and the version. You must copy it exactly.

The numbers are categorized on Chipset basis. If you don't know the chipset, just use Edit/Find in your browser and search for your BIOS Number. This page is more extensive than Award's (Phoenix) own publicized list!

  • You don't know which one to choose ? Then take this advice: Go to all the companies websites and compare specs, pictures, manuals with your board. It is possible that some of the above models are the SAME board but I can't garantuee you that a BIOS from another brand will work on your board.
  • The above BIOS numbers have bad BIOS encoding (it seems more like a date to me) so it's not that simple to find the manufacturer.
  • These boards are real cheap so you'll have to live with less support then a brand like e.g. Abit, Shuttle, Asus,...

  • You don't know which one to choose ? Then take this advice: Go to all the companies websites and compare specs, pictures, manuals with your board. It is possible that some of the above models are the SAME board but I can't garantuee you that a BIOS from another brand will work on your board.
  • These boards are real cheap so you'll have to live with less support then a brand like e.g. Abit, Shuttle, Asus,...

• Note: Normally T5 should correspond to a Tyan board, but it does not (bad BIOS encoding). t5 doesn't correspond to a Tyan board too.

All Asus BIOS ID numbers at the top of the screen, just above where the system memory count occurs, contain # 401A0 - XXXX.
The A0 indicates ASUS as the manufacturer the four digits following the dash indicates the BIOS revision level.  Thus it is easy to identify whether or not you have the latest BIOS version or not.
At the bottom of the same screen you have more information, in the following order; A date, which is the date of the motherboard manufacture, then the Chipset used, the model of ASUS motherboard and finally the revision of the motherboard.

• Identification Acer BIOS string: eg. ACR6BE00-M00-940825-R02-CO : ACR6BE00-M00 is the name of the motherboard; 940825 is the date; R02-CO is the version.
