The Command Prompt
After the computer has loaded MS-DOS from the hard disk,
you see the MS-DOS command prompt on the screen:
C : \ >
The command prompt tells you that your computer is ready to
receive instructions. It also identifies the current operating
drive: A or C, for example. The command prompt appears on
the screen whenever you load MS-DOS, complete an MS-DOS
command, or exit an application program.
In your computer, the diskette drive is A and the hard disk
is drive C. If you have an optional second diskette drive,
MS-DOS identifies it as B.

Copying System Diskettes
Now that you have started your system and loaded MS-DOS,
it is important that you make copies of your MS-DOS and
Reference diskettes right away. Use the copies (called working
copies) as they are needed and store the originals in a safe
place.
Note
If you have only a single diskette drive and no hard disk
drive, see "Using DISKCOPY With One Drive Only" in
Chapter 4 for instructions on copying diskettes.
Each of the system diskettes is formatted for 360KB.
(Formatting prepares a diskette to store data and is described
in Chapter 3.) To copy them, you need four 360KB double-
density, 5¼-inch diskettes.
