The node created for the DOS partition may be readable/writable by all. You make this choice when prompted whether to make the DOS partition public. If the node is not made public, then you must enter the user login name at the next prompt, and the node is made private to that user.
If multiple DOS partitions are found, each one is given a unique node name. The node name is printed for each DOS partition that is found.
The dosslice command is needed only when DOS is installed after UNIX has been installed.
