A/UX 2.0 doesn't support the SCSI manager; in general, you can't
(and shouldn't) access the hardware directly from user programs.
Most programs that get away with this under Mac OS (e.g. accessing
SCSI, ADB, ASC and serial [e.g. for MIDI] chips directly) fail
under A/UX.

Use a personal system folder.

There's something that's probably easy to figure out, but may not
be obvious to Mac OS users trying out A/UX (other Apple folks 
correct me if I'm wrong on this :-) ): if all your login accounts
use the global system folder, then the desktop database and file
system cache will have to be rebuilt whenever a different user
logs in.  In particular, opening folder will cause the system
to generate this information for the files in that folder.  If 
you have a personal system folder, this information is saved
from session to session. If you don't, it can be lost if another
user logs in.  There's a handy command to generate a personal
system folder.  It's called "systemfolder."
