Hardware Information under Linux

For most of the time I have been using `lshw` (list hardware) happily under Ubuntu. But yesterday, I had a situation wherein I need to find out the hardware of the machine in Rocks Linux. I did not think of installing `lshw` on the machine, but wanted to find out whether there are other commands from where I can get the hardware information including BIOS. So after doing some  google search, came up with `dmidecode`.

`dmidecode` is a tool for dumping a computer’s DMI (Desktop Management Interface) 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.

Usage:

root@ophiophagus:~$ dmidecode -t
dmidecode: option requires an argument — t
Type number or keyword expected
Valid type keywords are:
bios
system
baseboard
chassis
processor
memory
cache
connector
slot

root@ophiophagus:~$ dmidecode -t bios < List BIOS information>

Use the above types for getting the hardware information for the machine.
