2. If you have just made a change in your system’s
configuration, your computer may take a few minutes to
complete its power-on diagnostics. The first time you turn
on your computer after making such a change, it can take
up to five minutes to finish its self test, depending on what
you changed. If the computer does not display the MS-DOS
prompt after five minutes, press the
RESET
button and try
again. If that doesn’t work, insert the Reference diskette in
drive A and press the
RESET
button. If the computer still
does not boot, contact your Epson dealer.
3. Did you enter the correct password? See “Password
Problems,” below.
4. Could your software be causing the problem? If you are
running an application program, see “Software Problems,”
later in this appendix.
5. The problem could be caused by your keyboard. See
“Keyboard Problems,” later in this appendix.
6. If you want to stop whatever the computer is doing and
return to the MS-DOS command prompt, hold down the
key and press (or press [cl). See Chapter 3 for
more information on stopping a command or program.
7. If your computer still does not respond, you can reset it
using the command or the
RESET
button. See “Resetting Your Computer” in Chapter 3 for
more information.
8. If resetting the computer does not work, turn off the
computer and wait at least five seconds. If you do not have
a hard disk drive, insert the Startup diskette in drive A;
then turn on the computer. It should load MS-DOS.
