How to Find Motherboard Model and Serial Number in Linux
If you ever wanted to update your BIOS or make any other hardware changes to your Linux system, you likely needed the motherboard information. There is a handy little command line tool called dmidecode that we have written about in the past. This program will dump a ton of information about the hardware on your system. It's name is short for DMI decode because it can display all the information in the DMI Table (SMBIOS). In this case we are going to use specific switches to find the motherboard model and serial number in Linux system.
dmidecode is a tool for dumping a computer's DMI (some say SMBIOS ) table contents in a human-readable format. This table contains a description of the system's hardware components, as well as other useful pieces of information such as serial numbers and BIOS revision.dmidecode man page
To get your motherboard information simply use
dmidecode with the
--type option. The DMI type we are looking for is "Base Board" which is represented numerically using the number 2. Here is an example.
Of course you can use grep to find specific info. This is helpful if you are using it in an automated fashion like a bash script.
[[email protected] ~]$ sudo dmidecode -t 2 | grep -i serial Serial Number: 401
There is a lot this tool can do, this is barely scratching the surface. This tool is what you need to get any kind of hardware information from the command line. As we demonstrated, you can easily find the motherboard model and serial number in Linux using dmidecode.
