INT 31 - DPMI 0.9+ - PHYSICAL ADDRESS MAPPING AX = 0800h BX:CX = physical address (should be above 1 MB) SI:DI = size in bytes Return: CF clear if successful BX:CX = linear address which maps the requested physical memory CF set on error AX = error code (DPMI 1.0+) (8003h,8021h) (see #03143) Notes: implementations may refuse this call because it can circumvent protects the caller must build an appropriate selector for the memory do not use for memory mapped in the first megabyte SeeAlso: AX=0002h,AX=0508h,AX=0509h,AX=0801h,INT 21/AX=250Ah,INT 21/AX=EB05h
