If you are using one or more MDA, Hercules, or CGA
display adapter cards, you may need to change the setting of
jumper J4 inside your computer. The jumper tells the
computer whether you are using a color or monochrome
monitor. (Jumper J4 is set to the color monitor position at
the factory.) If the jumper is set incorrectly, you see one of
the following messages:
401
CRT ERROR
501
CRT ERROR
If you are using two different types of video cards, set jumper
J4 to the primary monitor type. You may also need to
change this jumper later if you change the type of monitor
you are using. See “Changing the Jumper Settings” in
Chapter 5 for instructions.
Password Problems
If you set a power-on password using the Setup program, you
must turn on your computer and enter this password before you
can use the system. When you turn on the computer, the screen
displays a key prompt
). If you do not enter the correct
password, you see an X on the screen to indicate it is incorrect.
The computer gives you a second and third chance to enter it
correctly.
If after three tries you have not entered the correct password,
the computer locks up and does not respond to your keyboard
entries.
Note
If you enabled network server mode when you set a password,
you may not see the key prompt. For more information, see
“Using Your Computer as a Network Server" in Chapter 4.
