AH = 64h DX = 0007h (function number) CX = 636Ch (magic value, "cl") BX = 0000h (indicates special request)
Return:
AX = call gate address
Notes: If CX is not 636Ch on entry, INT 21/AH=6Ch is invoked, because a bug in OS/2 1.x FAPI erroneously called AH=64h instead of AH=6Ch. Used by WinOS2 to make direct calls to OS2KRNL, bypassing the overhead of DOSKRNL
