hi,

thansk for ur replies.

yeah i suppose physical access is the best form of protection.

in terms of bios password and setting not to boot from cd etc, is it not possible to - if you have access to the motherboard - flip one of those jumpers on the motherboard to reset the bios? somebody told me that ....i think.

On another note, if someone has used knoppix to access the computer, i presume the only thing that would be able to detect it would be the RAM? is this right? how would it be possible to flush what is in RAMN out to see if knoppix was run. any ideas?

any help much appreciated.
