A friend of mine owns SCO Unix 3.2 and says that for him to boot MS-DOS,
he must boot from a floppy. Now, I have worked with XENIX and know that
the machines we had allowed you to pick the OS to boot with. This was
achieved by typing DOS at boot time to boot the DOS partition, or CRLF to
default to XENIX.
My question is, why can't my friend boot DOS from his hard disk? Is it
related to the order that the operating systems are loaded? I realize that
FDISK (MS-DOS) changes the active partition, but I sense there's a smoother
way of accomplishing this, such as XENIX does.
Thanks,

In order to boot DOS I have to change the active partition to my DOS partition, and then shutdown and reboot. SCO Unix only recognizes DOS partitions for MS-DOS versions 3.3 and earlier. Check the version of DOS that your friend has installed. This is true for booting and the DOS utilities (doscp, dosdir, doscat, etc...). This is a headache for me because I need a DOS partition > 32 MB, but I also want Unix to recognize it. Oh well, sacrifices must be made... Rich P.S. I found this documented in the "Open Desktop Release Notes" page 41
