Are you sure you are not colliding with your second serial port ?

Perhaps your CD drive is set to the same target as the controller.
Change the SCSI address jumpers of the _drive_.

To something else. Skip 0 and 7, as FD controllers may be set to both.

The multiple IDs have nothing to do with BIOS addresses. In fact, you
don't need the BIOS anyway.

you will get this _if_ you change disks - the drive checks its door.

This happens if you copy a CD to a file (with dd) without knowing what
you're doing.
