Sega, near the end of the Dreamcast's life, began making DC's that couldn't read CDRs. I've never come across one, though. I even just bought one and it boots up my Genny emulator just fine. I think I also read somewhere that these DC were only sold in Japan...but I could be wrong.
Find yourself one of the Sega Sports edition ones (in the black case w/ NBA & NFL 2K or 2K1). Those work fine. Or find one in the old white and orange boxes. With either of those, you'll be able to boot your import of Shenmue 2.
According to info earlier in that slideshow, there are only two sessions, and I was thinking of tracks. Still, there's no mention of the "dummy track" that I remember (and I know it was mentioned somewhere as I also remember a blurb saying that the mastering program generated it so as not to need a huge file containing nothing). Oh well.
