Mode on page 161 for details Splash Screen The Splash screen feature provides a user configurable splash screen image that is loaded to the framebuffer at the earliest possible time by the EPOG feature and EFI graphics driver and remains in place until overwritten by the OS or driver Additionally the Intel EMGD can be configured to suppress OS drawing to the on screen framebuffer until notified by an application Instead drawing is redirected to an off screen framebuffer When notified by the application the Intel EMGD will flip the already prepared off screen framebuffer to be on screen and cease redirection of drawing In this manner the configured splash screen will be displayed early during boot and remain in place until a time when the OS is fully loaded and the application interface has been prepared The splash screen is limited to 500 KB in size and JPG and BMP formats For Quickboot only BMP format is allowed Quickboot The quickboot feature optimizes the speed that Intel EMGD loads at the expense of compatibility and ease of use Quickboot disables non critical features that affect the initialization time of the driver that are not needed for targeted embedded applications For example there is no port detection it supports only an LVDS interface Splash Video The Splash Video feature provides a mechanism to use a portion of the off screen pre allocated video memory Stolen Memory as a video image
