1.  Attach CDs to SCSI bus.
2.  Reboot.
3.  The CDs will appear automatically.

You may have to make the actual devices for these (run /dev/MAKEDEV cd?
where ? is the number of the CD you want to add).  If you look at the boot
messages (in /var/log/messages or by running `dmesg') you can see which
CDs were attached to which devices.  For instance, I have two SCSI CDs:

Oct 20 17:23:05 gdi /kernel: ncr0 <ncr 53c815 scsi> rev 3 int a irq 10 on
pci0:1
2
Oct 20 17:23:05 gdi /kernel: ncr0 waiting for scsi devices to settle
Oct 20 17:23:05 gdi /kernel: (ncr0:2:0): "PLEXTOR CD-ROM PX-4XCE 1.00"
type 5 removable SCSI 2
Oct 20 17:23:05 gdi /kernel: cd0(ncr0:2:0): CD-ROM 
Oct 20 17:23:05 gdi /kernel: cd0(ncr0:2:0): 5.7 MB/s (175 ns, offset 8)
                             ^^^ see here

Oct 20 17:23:05 gdi /kernel: cd present [332530 x 2048 byte records]
Oct 20 17:23:05 gdi /kernel: (ncr0:4:0): "SONY CD-ROM CDU-76S 1.1c" type 5
removable SCSI 2
Oct 20 17:23:05 gdi /kernel: cd1(ncr0:4:0): CD-ROM 
Oct 20 17:23:05 gdi /kernel: cd1(ncr0:4:0): 5.0 MB/s (200 ns, offset 8)
Oct 20 17:23:05 gdi /kernel: cd present [400000 x 2048 byte records]

My Plextor is mapped to cd0 and the Sony is mapped to cd1.  

Hope this helps.
