Starting and Exiting MS-DOS

Before you can run an MS-DOS application program, MS-DOS must be running in memory. Chapter 1 describes how to load MS-DOS on your computer.

If you have the Apex 100\20, the computer loads MS-DOS from the hard disk automatically when you turn on the computer. If you do not have a hard disk, you need to insert your working copy of the MS-DOS Startup diskette in drive A and then turn on the computer to load MS-DOS. (Alternatively, you can turn on the computer and then insert the Startup diskette to load MS-DOS.)

If the date and time prompts appear, press Enter to accept the date and time shown. The screen then displays the MS-DOS command prompt, A> or C>. This tells you that MS-DOS is loaded and identifies the current drive.

Before you turn off the computer, make sure the A> or C> prompt is displayed. Then remove your diskettes, turn off your computer, and turn off any peripherals.

Starting An Application Program

Once you have loaded MS-DOS, you can start using your application program. If you have the Apex 100, remove the Startup diskette from drive A and insert the program diskette in that drive. If you have the Apex 100\20 and you already copied the application program to the hard disk, log onto drive C (and the appropriate directory, if necessary). If the program is not on the hard disk, insert the diskette in drive A.

Then enter the necessary command to start the application program, as described in the program’s manual. From this point on, until you return to the MS-DOS command prompt, refer to the application program’s manual for any instructions on using the program.
