Re: 8254 timer woes

:Is is possible to fault on special port IO so that we can prevent 
:legacy BIOS/programs to destroy our timing?

    Yes, basically the only way to fix the BIOS 8254 issue is to
    emulate I/O accesses to the 8254.  Would someone be interested
    in starting such a project?  It would not actually be all that
    difficult to do, though it does require some assembly knowledge.
    The 8254 has 3 identical timers with something like 5 modes of
    operation, counting, and latching state.
