Introduction

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.

A much easier way to get the Award/AMI BIOS number & possible manufacturer is by using CTBIOS v1.5. 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 ctpci330.zip.

If you have an AMI BIOS you can also try the AMIBIOS Motherboard ID Utility (written by AMI) (Click here to visit the AMI BIOS number page.)

Let's show you an example of an Award BIOS id: 2A59IZ1DC-00

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.

Identifying the chipset

As noted above the first part of the Award BIOS Number identifies the chipset used. The following is a list of all the ids and their corresponding chipsets. Follow the links to get a list of  known BIOS numbers for a particular chipset.

Note that when the BIOS begins with a 2 then the Award BIOS core version is 4.50 or 4.51. If it starts with a 3 this means the BIOS core is version 4.60. BIOS Numbers that start with a 6 have a Award BIOS V6.00 core
