The register state from the RealModeState field of ThunkContext is restored just prior

the 16-bit real mode code must be populated by the caller at SS:ESP prior to calling this function.
The 16-bit real mode entry point is invoked with a 16-bit CALL FAR instruction,
so when accessing stack contents, the 16-bit real mode code must account for the 16-bit segment
and 16-bit offset of the return address that were pushed onto the stack. The 16-bit real mode entry

If EFLAGS specifies interrupts enabled, or any of the 16-bit real mode code enables interrupts,

the IDT at address 0 is initialized to handle any HW or SW interrupts that may occur while in 16-bit real mode.
