I know that I can get the selector No. You must use assembly. I've been looking for it too. I've been thinking about making a _go32_dpmi_chain_protected_mode_interrupt_vector_or_not_depending_on_return_value() or otherwise suitably named but I haven't done any more than thinking it would be good to have one. Right, MartinS
