manufacturer for help.

m The Floppy Disk Maker screen will appear every time you start up your
computer until you make at least a minimum set of disks. It is very
important that you make a minimum set in case you ever need to reinstall
system software. If you still want to stop the Floppy Disk Maker screen
from appearing without making at least a minimum set, you can remove
the Floppy Disk Maker alias from the Startup Items folder (in the
System Folder).
When I start up the computer, I see a message about the system software.
m The system software on the startup disk you’re using may be incomplete or
damaged, or may be the wrong version. Make sure you’re using the correct
disk as a startup disk.
m If you’re sure you’re using the correct startup disk, you may need to reinstall
system software. See “Reinstalling System Software” in Chapter 8.
