I got replies from:
--- bernards@ecn.nl (Marcel Bernards)
--- mdl@cypress.com (J. Matt Landrum)
--- Mike Raffety <miker@sbcoc.com>
--- baumann@proton.llumc.edu (Michael Baumann)
--- Wilson N G <noel@essex.ac.uk>
--- ldavis!woden!gunn@snowbird.central.sun.com (David Gunn)
The replies fell into 3 groups:
1) I want to know too!
2) Buy a multi-disc CDROM.
3) The config file is missing a new line at the end.
I just got #3 from David Gunn and he was right on the money! I fixed
up the missing newline and all is well.
Someone asked about doing this with two SCSI interfaces,
unfortunately, I can't speak on that situation since I want two
CDROM's on one interface. I had removed all references to scsibus1
from the file. That also was not the problem.
Something others might be interested in:

And the correct answer! Thanks David!

} Without looking into it at all, I would guess that you may not have
} a RETURN at the end of the last line, or else that the line for target 5
} needs to come before the line for target six.
