I would guess that you do not want the second drive boot record on the
MBR. You should probably point it at a partition boot record now, rather
than the boot record of the entire drive. If your /boot/ is hda1, then
change it from hdb to hdb1. Run lilo. Then set your pointer in the BSD
boot loader (I've never used it, don't know how it works) to point at
the partition boot record for the hdb1 /boot/ partition instead of hdb
as a whole.

If you set the jumper on the drive to make it a slave, and it is on a
new cable to a separate controller, this might be incorrect. To be a
slave it must be the second drive on a cable with a master. If you have
2 drives and they are on different controllers, neither will be a slave.
I think an IDE cd rom drive can work as a master or slave also. Been a
long time since I played with IDE though, I'm a bit rusty (scsi is so
nice!).
