i posted this in the general hardware subforum but its probably more relevant here, sorry for the double posting.

im trying to boot a Knoppix (Linux) live cd and ive tried

1. Changing the boot order
2. selecting the cdrom as the boot device

and none has worked.

could someone post a solution please?
