Making software disks
This section describes how to create floppy disks of the software that comes
on your computer.
Why make software disks?
Your Macintosh PowerBook computer comes with different kinds of software
installed.
System software is the set of programs and other files that your
computer uses to start itself up, keep track of your files, and run application
programs. When you turn on your computer, it looks for a disk that contains
the system software. System software is always in a folder called the
System Folder.
Other included software gives you added functionality on your computer.
You need to make a copy of this software for safekeeping in case you ever
need to reinstall the software on your computer. The disks you need to install
and reinstall software from are called installer disks. You use the Floppy Disk
Maker application program to create your software installer disks.
What is a disk image?
A disk image is a discrete electronic representation of an individual disk.
The Disk Images folder in the Floppy Disk Maker folder on the CD contains
the disk images you need to create installer disks for both your system
software and the other software that was installed on the hard disk at the
factory. When you use Floppy Disk Maker, it copies the disk images onto
floppy disks. When you are finished making a set of disks with Floppy Disk
Maker, you’ll have a set of installer disks and will be able to reinstall the
software that comes on your computer.
