Does anyone know how to access the first disk partition (MSDOS drive C:) under xenix as vpix drive C:? Is it possible to "boot" vpix from this partition? Thanks, John ..!uunet!smosjc!john

I tried and got zip! Who knows, when VP/ix actually works we may by able to do quite a few usefull things with it... Jeff (Spectra Software) Harrell

This poses a considerable security risk, since /dev/hd00 addresses your ENTIRE hard disk (including fdisk and badtrack tables, all filesystems, etc.) This is necessary because MS-DOS requires access to the fdisk table. Also, VP/ix opens the device for exclusive use, so only one user can use it at a time. And since VP/ix opens all devices for read/write, it is impossible to set up your DOS hard disk partition as read-only. Yes, you can boot from your DOS partition, although I would recommend against it. The version of MS-DOS shipped with VP/ix has some modifications to make it less of a CPU hog (emphasis on "less of," it still is a CPU hog) in terms of spin loops and such.
