From time to time, for upgrading or replacement needs, I need to know which motherboard, CPU or chipset is in my server. For lots of machines, I know these details, for others, I have to look them up every time.
Some time ago I stumbled upon a great tool dmidecode which displays all DMI data, and I must say it displays A LOT!
For reference, the dmidecode explanation I used can be found here.
Just in case I forget it again, and have to look it up once more…
