The Toolbox ROMs, right? I can see the utility of using that (I mean, beyond that you might need to use it to boot), but why couldn't A/UX call those APIs itself? I can easily see where bootstrapping through Mac OS would be easier, but I can't immediately see why it would be particularly necessary.

It's been a long time, but I'm pretty sure A/UX didn't use any of the toolbox roms and had it's own drivers (we had the source). A/UX booted from a MacOS partition because the Mac bootloader only understood booting MacOS (and it wasn't writeable with new boot code), so you booted to MacOS, then started SASH, which loaded Unix.

That's exactly the reason. NetBSD uses its own booter for the same purpose, for example.
