7. If your computer still does not respond, you can reset it using
the Ctrl Alt
Del command. If that command doesn’t work,
you can reset the computer with 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.
9. If you installed an EGA or VGA display adapter card, or
another type of card that you want to be the primary display
adapter, you must set jumper JP14 to disable the built-in
VGA adapter. Otherwise, you will not see any display on
the screen. See “Changing the Jumper Settings” in Chapter
5 for instructions.
If you are using one or more display adapter cards, you may
also need to change the setting of jumper JP12. This jumper
tells the computer whether you are using a color or
monochrome monitor. (JP12 is set for color at the factory.)
If the jumper is set incorrectly, you see one of these
messages:
❏ 401 CRT error
❏ 501
CRT error.
If you are using two different types of video cards, set jumper
JP12 to the primary monitor type. You may also need to
change the setting later if you change the type of monitor
you are using. See “Changing the Jumper Settings” in
Chapter 5 for instructions.
