The Reference diskette also contains files for the System diagnostics program. Because you should always run this program from the Reference diskette, do not copy these files to your hard disk.

The Utility diskettes contain VGA drivers that allow you to display graphics in certain high-resolution modes. If you want to use any of these extended modes on your VGA monitor, copy any VGA files you need to your hard disk. See the

VGA Utilities Guide for instructions.

Note

Be sure to make backup copies of your Reference and Utility diskettes.
