Turn off the computer, wait at least five seconds, and then turn it back on. After the computer completes the power-on self test, the screen displays the date prompt. Press Enter twice to accept the date and time shown.

The C> prompt displays, indicating that the system has successfully loaded from your hard disk.

From now on, each time you turn on or reset your computer, it automatically loads MS-DOS from the hard disk. Just make sure drive A is empty.

Drive Assignments

MS-DOS always recognizes the hard disk as drive C. The diskette drive on the right side of the computer is drive A. If you have connected an external diskette drive to your Equity LT, MS-DOS identifies it as drive B, unless you have turned off DIP switch 2 on the back panel to make the external drive A.

Hard Disk Power Switch

The hard disk in your Equity LT has its own power switch. Leave this switch on at all times unless you will be using the computer without the AC adapter; in this case you may want to turn off the hard disk when you are not using it to conserve the battery’s charge. If so, see “Turning Off the Hard Disk” in Appendix A.

When you turn off the computer, it automatically turns off the hard disk even though the switch is on.
