Abstract

Techniques for selecting a boot display device in the multi-GPU configured computing device include a graphic initialization routine for determining a topology of a plurality of GPUs. It is then determined if a display is coupled to any of the plurality of GPUs. The determination of whether the display is coupled to a GPU is communicated to the other of the plurality of GPUs based upon the determined topology. Thereafter, selection of a given GPU as a primary boot device, by a system initialization routine, is influenced by representing each GPU not coupled to the display as a graphics device and the GPUs coupled to a given display as the primary boot device if one or more displays are coupled to GPUs, and by representing the given GPU as the primary boot device and all other GPUs as graphics devices when the display is not coupled to any of the GPUs. In addition or in the alternative selection of the given GPU as the primary boot device may be influenced by hiding the expansion ROM of GPUs not coupled to a display.
