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.

Let's show you an example of an Award BIOS id:


The first 5 characters identify the chipset. 2A59I stands for the Intel Triton TX chipset. You can find an extensive list of chipsets if you scroll down a bit.

The sixth & seventh character identify the manufacturer: in this case it's Z1. If you look at the Award Hardware Vendors list (see below) you'll find that the manufacturer is Zida/Tomato

The 8th character (most of the times, not always!) identifies the model. I say 'most of the times' because the manufacturer can use the same 8th character for all models based on a particular chipset!.

The C-00 at the end doesn't mean much.

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!

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.
