-
- Returns the properties of this real mode thunk implementation. Currently

- and the minimum stack size.
-
-Arguments:
-
- MinimumStackSize - The minimum size required for a 16-bit stack.

-Returns:
-
- The minimum size of the real mode buffer needed by this thunk implementation
- is returned.

-Routine Description:
-
- Tell this real mode thunk implementation the address and size of the real
- mode buffer needed.
-
-Arguments:
-
- ThunkContext - The thunk context whose properties to set.
- RealModeBuffer - The address of the buffer allocated by caller. It should be
- aligned on a 16-byte boundary.
- This buffer must be in identity mapped pages.
- BufferSize - The size of RealModeBuffer. Must be larger than the minimum
- size required as returned by AsmThunk16GetProperties().

-Routine Description:
-
- Make a far call to 16-bit code.
-
- NOTE: This function must be called on TPL_HIGH_LEVEL or with interrupts
- disabled because of GDTR and IDTR manipulations.
- This function must be placed in identity mapped pages.
-
-Arguments:
-
- ThunkContext - Thunk context to use.
- RegisterSet - CPU registers would be set to the values contained in this
- structure before making the far call. Then CPU registers are
- copied back to this structure.
- CS:EIP points to the real mode code being called on input.
- SS:ESP points to the real mode stack if THUNK_USER_STACK is
- set on input, otherwise ignored.
- EFlages is ignored on input.
- On output, values of CS, EIP, SS and ESP should be ignored.
- ThunkFlags - 2 flags have currently been defined, THUNK_SAVE_FP_STATE and
- THUNK_USER_STACK.
- THUNK_SAVE_FP_STATE - FPU state would be saved/restored
- before/after calling real mode code.
- THUNK_USER_STACK - The stack specified by SS:ESP would be
- used instead of the default stack.
-
-Returns:
-
- RegisterSet is returned.

-
-Arguments:
-
- ThunkContext - Thunk context to use.
- IntNumber - The ordinal of the interrupt handler ranging from 0 to 255.
- RegisterSet - CPU registers would be set to the values contained in this
