Yes, you can do that.  However, perhaps you can do something without the
floppy.  We have put QNX on one C: partition and DOS on another C: partition.
Then we use the 'fdisk' utility (which fortunetly lives on both OS's) to select
the partition to use for booting.  

Granted, I know nothing of XENIX, or why this works for that matter...
