That FDC is not an XT-IDE, it's a copy of Sergey Kiesev's XT-FDC controller. The same seller also saw fit to "cost optimize" the open source XT-IDE rev 4 and remove my copyright/site info. It's no great step forward, it's merely a copy of someone else's work with no attribution.
The controller chip used on that FDC is the same as found on some Adaptec AHA-15xx series cards, which have been the go-to for a long time on adding FM support to PCs whose onboard controllers don't support it.
