First, make sure you're not using "cable select" on the drives. Ensure
the original one is jumpered as "master" and the new one as "slave".
Cable select is probably the worst farking idea since IBM decided to
"flip" the floppy drive select lines on the ribbon cable rather than
use the jumpers on the drive.
It might help also if you put the CD on the secondary controller all
by itself. In other words, put both hard drives on the primary IDE
controller (one "master" and one "slave") and the CD (and other, slow
"secondary" storage) on the secondary IDE controller.
