@claudiom Basilisk II isn't capable of running A/UX, because A/UX requires an MMU (memory management unit) and B2 doesn't emulate that - it's the same reason you can't run Linux or NetBSD on B2.

Yes, you can run the “A/UX Startup" application from Mac OS, but you won’t ever be able to boot A/UX itself, even if you create all the partitions and copy the files over by hand.

There are two options for running A/UX under emulation:

1. QEMU (recommended)

2. Shoebill (less recommended as it bypasses the Mac OS launcher and boots A/UX directly)

@smallsco Thanks for responding. Yeah, I was bored and wanted to see how far I could go.  Shoebill I've known about for a while now, but back then I couldn't get it to run right, more than likely my fault. It's not in the OpenBSD binary ports, so I'll have to try that in Linux. QEMU is also an option, but I'd rather Shoebill.

Nevertheless, I'm taking the Quadra 650 to work tomorrow to install it all there since, according to A/UX Penelope, the install takes quite a while.

@claudiom From my experience putting A/UX on my IIfx, the install itself doesn't take too long, it's everything else you need to do afterwards: the configuration, getting a local copy of jagubox set up, running updates..

There's a repo here with a script (systemupdate.sh) that will run the recommended updates for you once you've got a local mirror of jagubox: https://github.com/smallsco/Apple_AUX_3.1.1_Setup/blob/fix_typos/SystemUpdater/systemupdate.sh
