This call simultaneously saves the current mapping context
and restores a previous mapping context for all mappable
memory regions (both conventional and expanded). It first
copies the contents of the mapping registers from each
expanded memory board in the system into a destination
array. Then the subfunction copies the contents of a source
array into the mapping registers on each of the expanded
memory boards. |
