Copying System Diskettes
Now that you have set
up
your system and loaded MS-DOS,
it is important that you make copies of your system diskettes right
away. Use only the copies (usually called working copies) for daily
operation; store the originals in a safe place.
To copy your system diskettes, you need three blank, 720KB,
double-sided, double-density, 3 1/2-inch diskettes. Follow these
steps:
1. Write-protect your original system diskettes. This protects the
diskettes from accidentally being erased or copied over. The
write-protect device is a small switch on the lower-right corner
on the
back of the diskette.
To
write-protect
a
diskette, slide
the switch down toward the edge of the diskette so there
is a hole where the switch used to be. (For more detailed
instructions, see “Write-Protecting Diskettes,” in Chapter 4.)
2. Insert the Startup/Operating 1 diskette in the diskette drive if it
is not
there
already.
3.
Type DISKCOPY
and press
Enter.
