ABSTRACT:
A display control such as a virtual display adapter allows the advanced functions of a display controller to be utilized in a large area of memory in addition to the normal use in display memory. This large area of memory includes system memory, and efficient access to this large area of memory is permitted for normal system use. The display controller also functions with non-contiguous and non-resident bitmaps. The flexibility of demand-paged virtual memory is utilized for display tasks, as display bitmaps may be written to the large area of memory as well as the display memory.
