with new people *finally* getting their CD players, this experience
may be appropriate..

if, like me, you have added an external drive to a station with
an internal having SCSI ID#1, you probably set the external's
ID to 0 and made it the boot device, maybe swapping on the
internal. peachy.  except now CDPlayer.app doesn't work with
IDs 0 and 1 and you don't want to open the box to reset the
internal ID. so you set the external ID to 2 or more.

you then have to fix /etc/fstab (and perhaps /etc/swaptab) to
reflect the change that /dev/sd0a has become /dev/sd1a and
/dev/sd1a has become /dev/sd0a.  but when you reboot, you find
that the system boots off the internal, since it has the lower ID.

you try booting from the ROM monitor and saying
bsd(1,0,0)sdmach
but the system still mounts the internal as /

after mucking with fstab on both drives, you manage to make both
unusable, and single-user mode mounts the internal as read-only.

here you open the NeXTSTEP 3.0 release notes and learn about
booting (and reinitializing) from the CDRom.  Tucked away in 
there is how to boot from a higher ID drive (and left out of the
2.1 Sysadmin book). (and wish you had made that bootable floppy).

at the ROM monitor, say
bsd(1,0,0)sdmach rootdev=sd1a nbuf=128        /*or whatever*/
and you can listen to tunes.

i'm not sure how to get this much into the ROM monitor's p
option to set this semi-permanently, since it only holds 12
characters.  sd(1,0,0)-a at least prompts you for the root
device, but you can't have the larger nbuf.  wasn't there
something in Preferences to set the boot drive? no longer.
anyway, if you have fstab right and type the right thing at
the ROM monitor, things should go ok.  if not, don't blame me.
you probably didn't need the tunes that badly.
