You appear to be using ide-scsi emulation so you will have two steps to take. The first would be to remap fstab for the new mount points. hdd would change to hdc. The next would be to change the lilo options line from "hdc=ide-scsi" to "hdd=ide-scsi" Quick scenario: Edit fstab for the changes, Edit lilo.conf, Issue Lilo command to write the changes to disk. Shutdown computer. Move the cables physically setting the jumpers correctly, turn the computer back on and you should be in business. I just did something similar myself and it went through without a hitch. -- Bryan Phinney Software Test Engineer
