root password recovery

[Rajesh]

Thank you very much for your help. I have successfully changed the root
password. 

On Linux is there a tool or command to find the system hardware
configuration. "dmesg" command gave me some info about memory and cpu. How
can I find out the hard disk information?

Regards,
Rajesh.

Bring the machine up in single user mode.  When it comes up to the "#"
prompt, use the "passwd" command to change the password.  Then enter 
"exit" to let the machine reboot to normal mode.

If you don't know how to boot in single user mode, at the blue boot
screen, hit "CTRL-X".  At the resulting "boot:" prompt, enter
"linux single".
