Epson EQUITY 386SX/16 PLUS - Manual (Page 223)

Note
If your application program requires a monitor that
supports graphics but you have a monochrome
monitor, the results will be unpredictable.
8. 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 J1 on
the main system board to disable the built-in VGA
adapter. Otherwise, you will not see any display on the
screen. You may also need to set jumpers J3 and J5. See
“Changing the Jumper Settings” in Chapter 5 for
instructions.
9. If you are still having difficulty with your monitor, run
the Video diagnostic 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
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.)
