you must disable the onboard video controller. To do this, set

the video switch to the EXT position. The video switch is

located beneath the connector in the expansion unit's rear

option slot.

In addition, you must check the position of the DIP switch

located in the slot for the optional coprocessor and RAM card.

Remove the RAM card, if installed. The DlP switch is

immediately below the BlOS chip. If you are installing a color

video card, be sure that DIP switch 1 is OFF. If you-

installing a monochrome video card, be sure that DIP switch 1

is ON.
