Abstract
An information handling system with a touchscreen is disclosed. When the operating system has not been loaded or a driver of the touchscreen is absent, an embedded controller of the information handling system receives and presents touch input information from the touchscreen to a host processor by emulating the touchscreen as a legacy PS2 device. After the operating system is loaded and a driver for the touchscreen is running, the legacy PS2 device emulation is terminated and touch input information from the touchscreen is presented through an I/O interface to the host processor and processed by the operating system.
