Abstract
A dual mode touchscreen display disposed in an information handling system chassis proximate a keyboard selectively presents images from information generated by a central processing unit or from information generated by a secondary processor associated with the touchscreen display. An operating system executing on the central processor unit presents information at the touchscreen through a serial link by treating the touchscreen as a secondary display to a primary display integrated in the chassis. Alternatively, an application executing on the secondary processor presents information at the touchscreen independent of the central processing unit or the operating system. As an example, the touchscreen display presents a number pad under the direction of the operating system to accept number pad inputs or, alternatively, presents a number pad under the direction of an application running on the secondary processor to accept number pad inputs that are forwarded to a keyboard controller.
