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
