Note
If your application program requires a monitor that
supports graphics but you have a monochrome monitor,
the results will be unpredictable.
If you installed a display adapter card in
your computer, and
you want to use that adapter as your primary display adapter,
you need to change the setting of jumper J3 on the main
system board to disable the built-in VGA adapter.
Otherwise, you will not see any display on the screen.

may also need to set jumpers Jl and J5. See “Changing the
Jumper Settings” in Chapter 5 for instructions.
If you are still having difficulty with your monitor, run the
Video diagnostics tests, described in Appendix C. If the
diagnostics program indicates an error, contact the place
where you bought the monitor.
Diskette Problems
If you see an error message or have trouble accessing data on a
diskette, try the following steps:
1.
Did you turn down the diskette drive latch on a 5 1/4-inch
drive to secure the diskette in the drive? See Chapter 3 for
more information.
2.
You may have inserted the diskette upside-down or it may
not be inserted all the way. Remove the diskette from the
drive and reinsert it with the label facing up. Be sure to turn
down the diskette drive latch. (See Chapter 3 for detailed
instructions on inserting and removing diskettes.)
