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:

401CRT ERROR

501CRT 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 (+III ). 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.
