find out mainboard serial number
 

hi

Which linux tool can find out mainboard serial number?

THX

Have you tried dmidecode and lshw?

Or eventually... a torch! You might open the case and look at the serial number stuck on the mainboard (if not hidden by some device).

THX, but I mean without disassembling computer system, just checking using software.
I've already tried: lshw, dmidecode, hwinfo, hardinfo but still doesn't work.

Maybe this information is not available to the OS. Another chance is lshal:
if you cannot retrieve it with one of the suggested tools, I'm afraid your best option is the flashlight. If you're careful, you can open the case and look at the motherboard without shutting down the machine.
