Use
This is an internal call for OS use only and should not be used by user software. User software should use GraphicsV instead of interacting with the HAL directly.
Programs the video controller to initialise a display mode. RISC OS passes a standard VIDC List Type 3 as specified in PRM 5a-125. Note that this is a generic video controller list, and so VIDC in this context does not refer to any specific devices such as Acorn VIDC20.
The HAL is expected to set the video controller timings on this call. Any palette, pixel DMA and hardware cursor settings are controlled via other calls.
