Knoppix was succesfully installed using linboot.img for boot and some work has been done with it.

Then I decided to change the motherboard and make some changes to harddisk layout using partition magic. Now boot does not work any more. I even don't get a displayof the boot selection table of lilo.

How can I tell Knoppix/Debian Linux to accept the new motherboard and the changed partition layout without loosing all other configuration work? Booting from Knoppix CD still works, but I doin't know what to do next.
