PROBLEM SOLVING
Q19.
When using my joystick with the computer's built-in game port, some
of my games do not allow movement to the right or in a downward
motion?
A.
Some joysticks may not calibrate (function) properly with certain game
software applications that accept joystick input. If you connect a joystick to
the computer's built-in game port and you find that it does not work with the
game software you are using, try the following:
1.
Reposition the trim knobs on the joystick. (See the manual that came
with it for instructions.) Then try it again.
2.
If adjusting the joystick's trim knobs does not solve the problem, you
may want to purchase a joystick option card. Install the card as
described in Chapter 3 of the EL 486UC's User's Guide; then set
jumper J5 on the computer's main logic board to the 2-3 position to
disable the built-in game port. (See page 3-9 of the EL 486UC's User's
manual for instructions.)
Q20.
When the computer is powered-on, it completes the power-on self-
test, starts to boot off the hard disk drive but then locks-up. What
may be causing this problem?
A.
This problem may be due to an improper setting in the computer's SETUP
program. To insure proper system operation, always set the Shadow BIOS
ROM and Shadow Video ROM setup options to WP-Shadow.
The computer's SETUP program may be accessed by pressing CTRL, ALT
and "S" while at a DOS prompt or during the computer's boot process.
