Summary: UNIX & DOS Boot...


   Hello,
 What you say about creating a small partition on the C: drive with one
exception. What happens when you turn on the machine ?? It certainly
can't boot both OS's at the same time (can it). If you look at it logically
it makes sense that only one OS can have the boot tracks (track 0) on the
drive. Also IBM-XENIX (I believe this goes for the others as well) must 
have control of the boot blocks on drive C:, there for you can not install
the DOS boot tracks as well. I have set up several systems in which both
DOS and XENIX reside on drive C:, and there is no problem with that, all
you have to do is boot from a floppy when you want to use the dos partition
of the drive.

  Example:
 
c:
c:\
autoexec.bat


 If you put this in your autoexec on the DOS floppy, this will automatically
change to the DOS partition on the C: drive, and run the autoexec.bat file
that is on that drive. Be sure to install where you are keeping to OS 
commands on the C: drive in the autoexec.bat file (ie: C:\DOS). I hope this
helps clear up this issue...
