Int 31 Fn 0800 P - DPMI 0.9+ - Physical Address Mapping [E]
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 AX=0000h)
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
