Now that you have set up your system and loaded MS-DOS, it 

is

important that you make copies of your three system diskettes right away.

Use only the copies (usually called “working copies”) for daily use and store

the originals in a safe place.

The procedure for copying a diskette depends on whether your computer

has one or two diskette drives. Follow the instructions given for your model.
You will need three blank, double-sided, double-density, 

 720KB

diskettes.

Before you copy your system diskettes, write-protect them so you can’t

accidentally erase data. See Chapter 3 for instructions on write-protecting

diskettes. Also, label each copy you make right away.

1.

 the Startup/Operating 1 diskette in drive A if it is not there

already.

2. Insert a blank 

 

 diskette in drive B, the bottom drive.

3. Type the following and press 

Enter:

DISKCOPY A: B:

The screen displays this message:

Insert SOURCE diskette in drive A:

Insert TARGET diskette in drive B:

Press any key when ready . . .

4. Drive A already contains the diskette you want to copy (the source) and

drive B contains the blank diskette (the target), so just press any key.

.

If the diskette in drive B is not formatted, the DISKCOPY program
formats it. Then the program begins copying the data from drive A to

the formatted diskette in drive B.

5. When the copy is complete, the screen displays this prompt:

Copy another diskette (Y/N)?
