Many people want to find out their motherboard manufacturer without having to open their computer. In other cases, such as upgrading the BIOS and seeking drivers for the board, the manufacturer and model of a motherboard must be known.
The motherboard manufacturer can be found through the BIOS serial number. This number is shown onscreen (lower line) during the memory count that is always run when you turn your computer on. If you have never paid any attention, press the Pause key on your keyboard when the memory is being counted and you will be able to read the BIOS serial number from the frozen display. The same line contains important information, like the BIOS date. This information is important when you are considering upgrading your BIOS, to find out on the board manufacturer’s site whether there is or not a later version of BIOS than the one your computer is currently using (we have already explained how to upgrade BIOS. Please refer to http://www.hardwaresecrets.com/article/33, if required).
For instance, assume that that the motherboard indicates the following number onscreen while counting memory: 06/06/2002-VT8366-8233/5-JL6LVC0CC-00. Painlessly, we can deduce two things: the BIOS date (BIOS version) is 06/06/2002, and the motherboard uses VIA chipset VT8366 and VT8233/5, widely known as VIA KT333.
I will get into this and report back my findings. Jimmy-I apreciate your response. I opened up a case with Support One, but they said there is no way to do what I am asking, and the only way to change the serial number is by entering the bios during a reboot. Windows would no longer start because of an invalid product ID even though it had be installed for several years. Did a factory reinstall to attempt to fix. F1 System Information Shows the following. [email protected]) version: F.11. Serial Number: (empty- nothing is shown) UUID Number is 000-0000-0000000. You may also be able to find the serial number in the BIOS or UEFI firmware settings screen. This technique won’t get you a serial number if the wmic command didn’t, since the command pulls the serial number from the BIOS. However, checking the BIOS could be helpful if you can’t actually sign into Windows to run the wmic command.
What Is My Serial Number
There are three major BIOS software manufacturers, AMI, Award and Phoenix (Phoenix has recently bought Award). The format of serial numbers used by these manufacturers varies, as we will see below.
Deciphering Award BIOS
The format of BIOS Award’s serial number is shown in Figure 1, where we can see that the first five digits indicate which chipset is used by the motherboard, the next two digits indicating the motherboard’s manufacturer and the meaning of the remaining digits depends on the motherboard’s manufacturer.
Figure 1: Award Serial Number.
As you will notice, this information is encoded. To decode it, you must use a table given in http://www.wimsbios.com/numbers.shtml. Check the serial number used in the above example, of a PCChips motherboard with chipset VX Pro (which is a rebranded VIA Apollo VP1).
Deciphering AMI BIOS
The AMI BIOS serial number is longer than Award’s one. The motherboard manufacturer is coded in the last four digits of the third group of numbers, counting from left to right, as shown in Figure 2.
Figure 2: AMI Serial Number.
In the same way as Award BIOS, you will have to consult a table to determine the manufacturer corresponding to the number you have found. This can be done at http://www.wimsbios.com/numbersami.shtml. Check the serial number of our example, which is a motherboard made by PCChips.
No Serial Number In Bios Windows 7
The major difference between AMI and Award’s serial numbers is that the former usually contains information on the model of motherboard directly recorded in the serial number. For instance, serial number 61-1210-000747-00101111-071595-M747 is a PCChips M747 motherboard and serial number 51-0505-001437-00111111-071595-M1531/43-01-10-TX-PRO-0 corresponds to a PCChips motherboard using TX Pro chipset.
No Serial Number In Bios Update
Note that there are exceptions to the rules described, mainly when dealing with PCChips motherboards. Looking at the serial number of a M747 motherboard you can see that the manufacturer’s ID is an invalid number (there is no 0747 manufacturer); instead of identifying the manufacturer (PCChips), it is giving the model (M747). Whenever a motherboard’s serial number does not conform to the rules described, you may be dealing with a PCChips piece.
