...he registers on return to real mode. 16-bit pointers in a seg:off pair can be converted to a 32-bit pointer via: ptr = MK_PTR(seg, off); for example: ptr = MK_PTR(regs->es, regs->ebx.w[0]); /* ES:BX */ *** Calls from protected mode (32-bit) to real mode (16-bit): This is done via the core_intcall(), core_farcall() and core_cfarcall() functions, which are the direct versions of the analogous instructions in the com32 world. They are defined in <core.h>: void __cdecl core_intcall(uint8_t, const com32sys_t *, com32sys_t *); void __cdecl core_farcall(uint32_t, const com32sys_t *, com32s...
