How to obtain motherboard information under Red Hat

Here is a question I did not know how to answer, and I was glad to find the answer: "How do I find the serial number of the motherboard of a server, under Red Hat Linux?". Gosh, what a good question, let me fire up Google... And Google -- who is your friend (tm) -- delivered!

Use the dmidecode command and pipe the results into less, like so:

# dmidecode | less
# dmidecode 2.11

The output of dmidecode is very long and very detailed, so make sure you pipe it into something else to make sure you don't miss anything.

An interesting data, in the example shown above, is that the machine really is a virtual server, running under VMWare.

Hope this helps!
