I run SCO 2.3.1 on a 386 with a Logitech HiRez bus mouse and have no problems
in Xenix.  I also get the "10 bits of I/O address decoding" message at bootup.
The mouse is on the 2nd parallel interrupt (IRQ 5 I think).  Mouse comes up
everytime in Xenix, warm or cold boot.  However, the mouse is NEVER recognized
when I warm boot from my DOS 3.3 partition AFTER having run Xenix... it
always takes a cold boot in this situation to remedy the mouse with DOS.

Hope this helps.
