[comp.unix.xenix] DOS & Xenix on same drive

bob@consult.UUCP (Bob Willey) (08/04/90)

We are about to install a system for a client and want to install
both DOS and Xenix on the same drive.  I am familiar with the
basic procedure (FDISK for DOS, setup DOS FIRST) then install
Xenix for the balance of the drive.

BUT, the problem comes in with the limitations.  The drive on the
subject machines is 100mb.  According to the documentation we have
seen you can setup a max partition of 32mb for dos and use the
balance for Xenix.  What we would LIKE to do, is to setup 32mb
drive C for dos, 36mb for Xenix, and another 32mb drive for dos.
Is this possible on one physical drive?????

I have not found anything about this at all.  This will be a
Acer 1100/SX machine with an IDE 100mb drive.  2mb memory,
DOS 3.3, SCO Xenix 386 2.3.2, etc....
Any ideas?

Thanks for any input.

You can do this by allocating an extended partition of size 32mb from MS-DOS. 
That is, install a DOS partition (32MB), then use FDISK to install an extended
partition (32MB), then install Xenix.

But there is one drawback, Xenix dos command (ie, dosls, doscp, etc.) can access
the standard DOS partition only, you cannot access files from the extended
partition!
