Working with DOS
SCO OpenServer includes several DOS utilities that let
you access and manipulate files on DOS disks and
DOS partitions on your hard disk.
You must have a bootable, although not active,
DOS partition on the hard disk or a
DOS floppy disk to use these SCO OpenServer commands. For example, you
can only transfer a file from a UNIX partition on the hard disk to a
DOS floppy disk if either the DOS
floppy disk is bootable or there is also a DOS
partition on the hard disk.
Mounting DOS filesystems and accessing the files directly
with UNIX commands is faster and more efficient than using the
``Using mounted DOS filesystems''
for more information.
SCO OpenServer systems do not record bad tracks in the DOS area of
the hard disk. If a bad track develops in the DOS area,
an operation such as doscp that attempts to access the affected
area may fail (resulting in the
Error on fixed disk
When trying to use the DOS utilities to
access files on your DOS partition,
you may see the error message
bad media byte.
This message indicates that the DOS
partition on the hard disk is not bootable.
You can make your DOS partition
bootable by first backing up the files on the
DOS partition, booting DOS from
the floppy, and formatting the DOS partition using the command:
format c: /s
You should now reinstall your DOS files.

programs or applications from SCO OpenServer unless NeTraverse Merge is installed.
