Which IDE chip does DOSBox-X emulate?

[BridgeHeadland]

Question

First, I want to say that I deleted my last comment (which was chip related) in #3538 because I found that it clearly wasn't the case after all.
I see that the fdc, primary section has a chip setting and that is understandable since there is more than one type of FDC chip. Because the IDE sections do not each have their own chip setting, it is obvious that DOSBox-X emulates one specific IDE chip, which chip does it emulate? ICH6, ICH9, PIIX3, PIIX4, or something like that?

Have you checked that no similar question(s) exist?

For the time being, it's generic IDE emulation. It does not yet emulate the details of any specific motherboard chipset.

I can see the appeal of emulating the Intel PIIX chipsets since those are PCI IDE chipsets with support for IDE DMA. I had a Pentium system back in the day with the PIIX3 which Windows 98 handled quite well with DMA enabled, in fact it was good enough to capture video from a capture card at full frame rate quite reliably.
