Done. Is there an FAQ for this driver that has some of this info,
http://people.freebsd.org/~gibbs/linux/ is very sparse ..... also
modinfo aic7xxx with the various options does not provide much info
either ...

That is what I thought ...

Normally. At present it is external (doesn't fit in my desktop machine

According to the manual "the autoloader does not support termination on
the device itself".
Attached please find a diff to the previous dmesg, now with the verbose
messages, just after modprobe'ing aic7xxx, and the contents of
/proc/scsi/aic7xxx/1. Below are the last messages seen when running "mt
-f /dev/st0 status":
