- 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.
