hardware information

A lot of the info about the hardware is in the /proc file. If you type [ cat /proc/* ] you will get several thousand lines of info about hardware and memory locations. Perhaps a better way is to look in the proc directory and examine the individual files and directories; most of which have names reflecting their content;
or type [ cat /proc/* > hardware_file ] to send the ouput to   hardware_file.
For example, if you want to know the pci hardware that linux sees in your machine, type:
[ cat /proc/pci ]
