    SMSC chips are generally very capable as well.

    Thanks for your updates TestFDC.

    I did some test yesterday and have a question.

    CA9277B Advanced Super I/O Controller with N82077SL FDC.

    My problem sometimes is to find the correct result as on 360k floppy SD at 250 failed and on HD-floppy it was not tested.




    So I interpreted the Result as follows
    Code:
     Data  Rate
     250  300  500
     SDX  SDX  SDX
     FPF  PPF  PPF 
    
    
    
    Hardware SlotCPU AMD386-33  , Matrox VGA, 3C509 NIC

    I believe that I noted the inconsistent issue a couple of years ago. I believe I uploaded a much simpler version of the tool at the time.

    But the Intel 82077AA-1 definitely has issues with FM and doesn't do 128-byte MFM, period.
