AH = C7h DS:SI -> user supplied memory map table (see #00526)
Return:
CF set on error CF clear if successful
Notes: Call AH=C0h and examine bit 4 of feature byte 2 to check if this function is supported. IBM classifies this function as optional. Windows95 OSR2 reportedly does not support this function even though INT 15/AH=C0h indicates that it is available (observed on several different systems)
See Also: AH=C0h - AH=C9h - AH=D1h - AX=E820h
