 200  *         Real-Mode:   Seg*16 + LOWORD(Offset) + V86BASE
 201  *         16-bit:      convert (Seg, LOWORD(Offset)) to linear
 202  *         32-bit:      use Offset as linear address (DeviceIoControl!)
 203  *
 204  *       Real-mode is recognized by checking the V86 bit in the flags register,
 205  *       32-bit mode is recognized by checking whether 'seg' is a system selector
