I am interested in hardware interrupt programming too.
Well, I have a problem: I need to call the original interrupt code before
call my interrupt handler, how can I do this? I have used the function
go32_dpmi_chain_etc... but this routine chains the orignal interrupt code
*after* the user interrupt handler.

Is there in your tutorial a solution for this?
Could you mail-me a copy of your tutorial?
Thank you.
