The monitor does not display images correctly.
Make sure your monitor and display adapter card match.
Also, be sure any switches or jumpers on the card are set
properly. See the documentation that came with your
monitor and display adapter for instructions.
Be sure you chose the correct display adapter type in
the System Configuration program. Also check the
recommended switch and jumper settings. (See Chapter 2.)
If you are running an application program, see if you need
to configure the program for the type of monitor and
display adapter you have. Also, make sure you are using
the appropriate monitor and display adapter for your
software.
Diskette Problems
Be sure you turned down the diskette drive latch or pressed
the drive button to secure the diskette in the drive.
Check to see if you inserted the diskette upside down or if
you did not insert it all the way.
Check to see if you inserted the right type of diskette.
If the diskette is blank, make sure it is formatted.
Place the diskette in another drive and repeat the operation.
If this works, the trouble may be in your diskette drive. See
“Diskette Drive Problems” below.
Check to see if you entered an incorrect diskette drive type
when you ran the System Configuration program. See
