SELECTABLE GRAPHICS CONTROLLERS TO DISPLAY OUTPUT |
| 摘要 |
A computing system includes a plurality of graphics controllers, a reserved memory region, a shadow memory region, and a system Basic Input Output System (BIOS). The reserved memory region is to store a plurality of video Basic Input Output System (BIOS) images. The shadow memory region is to store a selected video BIOS image corresponding to a selected graphics controller, such that the selected graphics controller is to display output in response to a service request for video BIOS services, without use of a graphics driver. The system BIOS is to enable changing the selected graphics controller, based on copying a video BIOS image from the reserved memory region to the shadow memory region. |
