How can I use A/UX to make backup copies of my installation media? The
floppies don't have Macintosh file systems on them, so regular Macintosh
backup programs don't work.

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.
