6.3.2 Creating and Using a Backup Floppy Set
The IRIS 3010 includes several tools for making a set of floppies for backup and
using them to build a file system on the hard disk. The two procedures below
describe how to create the floppies and how to build the disk from them.
The floppy set is to be used only in extraordinary circumstances. There is no
need for the typical user to create the floppy set, as the backup partition on the
disk can be used if there is problem with the file system.
