New TestFDC Results Registry

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

 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.
