How to check Motherboard/BIOS/Processor/Chassis details from commandline

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.

-d, –dev-mem FILE Read memory from device FILE (default: /dev/mem)
-h, –help Display this help text and exit
-q, –quiet Less verbose output
-s, –string KEYWORD Only display the value of the given DMI string
-t, –type TYPE Only display the entries of given type
-u, –dump Do not decode the entries
–dump-bin FILE Dump the DMI data to a binary file
–from-dump FILE Read the DMI data from a binary file
-V, –version Display the version and exit

The most common option is the –type switch which takes one or more of the following keywords:

bios, system, baseboard, chassis, processor, memory, cache, connector, slot

dmidecode –t bios
dmidecode –t 1
