Starting MS-DOS

Before you can run an MS-DOS application program, MS-DOS must be running in memory. If you have prepared your hard disk according to the procedures described in Chapter 3, MS-DOS is loaded automatically from your hard disk whenever you turn on your computer (provided you do not have a diskette in the diskette drive).

When the date and time prompts appear, press Enter to accept the date and time shown. The screen then displays the MS-DOS command prompt, C>.

Exiting MS-DOS

Before you turn off the computer, make sure the MS-DOS command prompt (either C> or A>) appears on the screen. Then remove your diskettes, turn off any peripherals, and then turn off the computer.

Changing the Current Drive

MS-DOS identifies your hard disk as drive C. Your 3 1/2-inch diskette drive is identified as drive A. If you have an external 5 1/4-inch diskette drive, that drive is recognized as drive B.

Note

If you wish, you may reverse the drive identifiers for the internal

31/2-inch and the external 5 1/4-inch diskette drives by setting DIP switch 2 on the back panel in the on position. See “Setting the DIP Switches,” in Chapter 1.
