Award BIOS numbers

December 27, 1998

Statistics: NedStat Rating


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

Luckily each BIOS has a unique BIOS ID (= BIOS Number) which identifies the manufacturer,chipset,... of the board.

Let's take for example: 2A59CQ1CC:

This a typical Award BIOS Number. 2A59C stands for the chipset used; here it's the Intel Triton FX chipset.
Q1 stands for the manufacturer: QDI
CC stands for the model: P5I437/250A

Note that Q1 starts with a Q and that the manufacturer's name also starts with a Q! Because more then one m/b manufacturer can start with a Q, the Q is followed by a number.

The goal of this page is to create a list with BIOS numbers with their corresponding motherboards.

Therefore I need your input: Please send me your BIOS Numbers and also the corresponding manufacturer and model. You can use this form.

The 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.

A much easier way to get the Award/AMI BIOS number & possible manufacturer is by using Run it and it'll give you the BIOS number, possible manufacturer and more. If you want to know the name of your chipset you can also download

Before sending please check if your BIOS number and the manufacturer/model isn't already listed ! (This saves me a lot of time!)

I've made two pages: an AMI BIOS number page and an AWARD BIOS number page (which you are reading now). This page is more extensive than Award's own publicized list!

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.

I'm NOT RESPONSIBLE for mistakes in this list !

ASUS motherboard numbers

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.
