Copying the Reference and Utility Files
If you have a hard disk, you’ll probably want to copy some of the
files on your Reference diskette and Utility diskettes to the hard
disk. This allows you to run the programs directly from your
hard disk instead of having to insert a diskette into the drive.
Use the COPY command (described in your MS-DOS
Reference Manual) to copy the following files from the
Reference diskette to your hard disk:
AFDD.EXE COREFIX.EXE ESPEED.EXE
HDSIT.COM HDSIT.VER ROMBIOS.COM
The Reference diskette also contains files for the Setup program
and the System diagnostics program. However, you should
always run these programs from the Reference diskette in
drive A; so do not copy these files to your hard disk.
The Utility diskettes contain VGA utilities 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, you’ll
need to use some of the VGA utilities on the Utility diskettes.
It is best to copy the files you need to your hard disk as well. See
Appendix A for a list of the utilities and instructions for using
them.
