It's been a couple of years since I rebuilt my desktop, and since then, I've largely forgotten what hardware is in my machine.

So about a month ago, when I was adding some new hardware, I realised I couldn't remember what I was using. I thought "surely there's a better way than trawling through emails", and lo and behold, How do I find out my motherboard model? on AskUbuntu, which has a handy root and non-root variant.

However, as a caveat, this likely will not be accurate depending on if you are running in a Virtual Machine, i.e. on shared hosting.

Without Root Access

By running the following command:

$ cat /sys/devices/virtual/dmi/id/board_{vendor,name,version}
ASUSTeK COMPUTER INC.
X99-A II
Rev 1.xx

Which should be good enough for what you need!

With Root Access

If you have root access, there is the dmidecode command that can provide much better information, such as:

$ sudo dmidecode -t 1
# dmidecode 3.2
Getting SMBIOS data from sysfs.
SMBIOS 3.0.0 present.
