ABSTRACT:
In a computer system having an extension slot capable of detachably receiving a display adapter board and display hardware controllers for plasma and CRT displays, respectively, the display hardware controllers are disabled in initialization processing upon power-on. Thereafter, it is checked if a certain type of display adapter board is inserted in the extension slot. When the certain type of display adapter board is not inserted, the display control hardware element for the plasma or CRT display is enabled in accordance with display select data selected in setup processing. When the certain type of display adapter board is inserted, the incorporated display hardware controller interfering with the inserted board is disconnected from the system, and the display adapter board inserted in the extension slot is enabled to have a priority over the incorporated controller.
