linux system info

if you ever want to get low level h/w info from your linux installation and your proc file system is cryptic, use 'biosdecode' and/or 'dmidecode'

biosdecode is known to be inadequate. some recent versions of enterprise linux dont ship biosdecode by default. use dmidecode instead. however, it is known to be inaccurate or un-reliable. But, it gives a quick and easy peek into the system and if you need reliable data, you must anyway look into the proc fs.

'dmidecode -t' prints all available sub-system level info.
