Why use fdisk to go between DOS and Xenix.  I have tested Xenix for
possible inclusion on isolated PC's here at Colorado State University. 
When doing so I found quite by accident that at the Xenix Partion
managaer (bootstar loader)  prompt of

boot?

if you type in dos the DOS partition is automatically booted.  That way
you always get back to Xenix when you reboot unless you specifically
request DOS.  BTW this mechanism can also be used to test nex Xenix
kernels.  To do this name the new kernel something like xenix.new and at the 

boot?

prompt type in xenix.new.  Then if the new kernel works rename the old
kernel xenix.old and the new kernel xenix.
