Using the Alternate VGA Interface

Your computer includes an alternate VGA interface on the main system board. This feature allows you to install a high-resolution graphics adapter card in one of the option slots for your VGA monitor and still access the standard VGA signals provided by your main system board circuitry.

To connect the graphics adapter card interface to the alternate VGA interface, follow these steps:

1.Remove the computer’s cover as described in Chapter 3.

2.Set jumper J1 on the main system board to B to disable the built-in VGA display adapter. See “Changing the Jumper Settings” on page 4-4 if you need instructions.

3.If you have not already done so, follow the instructions above to install the graphics adapter card in your computer.
