To clone an A/UX installation floppy, follow these steps:
1) Give the command:
dd if=/dev/floppy0 of=/tmp/floppy.image
This creates a file containing a copy of the floppy disk contents on the
A/UX file system.
2) Insert the duplicate floppy and type:
dd if=/tmp/floppy.image of=/dev/floppy0
to move the copy of the A/UX file system to the new floppy.
As an alternative, you can make the backup copies under the Macintosh OS
using a program like DiskCopy.
