Int 31/AX=0305h

Return:
CF clear
AX = size in bytes of state buffer
BX:CX = real mode address of procedure to save/restore state
SI:(E)DI = protected mode procedure to save/restore state (see #03150)

Notes: The buffer size will be zero if it is not necessary to preserve state. 16-bit programs should call SI:DI, 32-bit programs should call SI:EDI. This function is only needed if using the raw mode switch service
