First, the only XENIX that supports the 154x adapter is version 2.3.2GT
from SCO.  2.3.1 does not support the 154x.  Second.  You mentioned that
the adapter failed to find target 0 at boot time.  You should have the
Maxtor drive set to target 0.  I think it is set to target 4 by default.
Reference the Maxtor docs for this.  The tape drive should be set to target
ID 2 or above.  In all cases you will have to know the target ID's of
both to install them under 2.3.2GT.
