Introducing The Software Disks

There are several standard 3.5-inch magnetic diskettes for each software part number. This group
of diskettes include the boot loader interface and the system operating software. You place these
diskettes (commonly referred to as floppy disks), into your personal computer (PC) in a certain
order just as you would any set of program disks.
The system operating software is unique for each of the three system sizes. Be sure that you
load the correct system software for the size system that you are installing.
