No, it doesn't enhance the native FDC in any way; rather it bypasses most of
it. It really is a separate "controller", using that term loosely. It allows
the PC to read and write raw channel data, bypassing the native FDC's FM & MFM
encoder and decoder. When using the card, the native FDC is only used to
select the drive and seek to the desired track.
