Make a Backup of Your System
Your computer comes with the necessary software already
installed for you to use the computer right out of the box.
However, on some computers, the
Diskette Factory
program is installed so you can create backup diskettes.
On other computers, you will find utility and device driver
diskettes packed in the box with the computer.
If your computer did not come with the utility and device
driver diskettes, make a backup copy of all necessary files
using the Diskette Factory. This way, if you ever need to
reinstall the operating system, you will have all the
necessary software you need to restore your computer to
the way it was at the time of purchase.
Do you need more hard disk space?
If your computer did not come with the utility and device driver diskettes, and
you have already made a backup
copy of all necessary software using the Diskette Factory , you can delete any preinstalled software you do not
want to use to have more free hard disk space.
Click on the Diskette Factory icon; then follow the instructions on the screen.
You can also delete the demonstration program.
You are ready to use your computer.
If you have any application programs to install, follow
the instructions in the documentation that came with
those programs.
If you are reinstalling the operating system...
If you are reinstalling the operating system to
customize your computer, follow the instructions on
page 177.
If you have any problems after you have customized your computer, refer to “Commonly Asked
Questions and Problems” on page 211 to solve your problem.
