What OS is installed on the hard disk?  What boot loader?  What happens
when you boot knoppix on this machine with the failed disk controller but
with the disk on the second controller?

If you're using grub the you probably need to edit the boot command to
tell it where the root partition is and it should boot in single user
mode at least.  Then just edit the fstab as necessary and the grub menu
file.

I've just had the same problem moving a hard disk onto a new machine and
putting it on the ATA133 controller instead of the built-in ide
controller.  I've still no idea how I'm gonna boot the Win2kPro
installation on the same disk without reinstalling it but that's par for
the course, innit?
