As many of you asked about "mysterious" jumpers of Sonic Buster 8 - I updated the home page with more details about jumper settings in the configuration section. Hope it will clear things up 😀

I believe my card is Rev-A but the BUSHLD jumper is closed by default, since that's the way I got it and I didn't change it. According to that doc it's in IORDY reset mode. I'm a bit confused what you mean by "default" in this case.
