DOS/32 Advanced DOS Extender - Programmer's Reference

2.38 - DPMI function 0602h - Mark Real Mode Region as Pageable

Advises the DPMI host that the specified memory below the 1 MB boundary may be paged to disk.


In: AX = 0602h
BX:CX = starting linear address of memory to mark as pageable
SI:DI = size of region to be marked (bytes)

if successful:
CF clear

if failed:
CF set
AX = error code

8002h - invalid state (region already marked as pageable)
8025h - invalid linear address (region is above 1MB boundary)


a) As DOS/32 Advanced does not support virtual memory this function is implemented for compatibility reasons only.
