    That sounds about right, there is an example programmed in Pascal
(though it's not difficult to "translate" into C). It's from the PCGPE, and
the file is PIT.TXT. It's at
http://www.cse.iitb.ernet.in:8000/proxy/stuff/programming/languages/assembly
/x86/gameasm/pit.txt
    The only thing you missed is that you must send the EOI (send byte 20
hex to port 20 hex) to the controller for all the times the BIOS handler is
not called.


See ya!
