Thanks for the tip! Any windows binaries? or a known good source dump?

not too surprising! Tearing a little into SheepShaver, and it’ll reveal that it is basically the same as Basilisk, it just hooks the 68000 code. Although the newer the version of MacOS, the fewer things it hooks in the 68000 code, until 9.2 where it’s all gone. Not to mention how 8.0/8.1 are far more stable than 8.5/8.6/9.0 … No doubt they pushed that PPC to the limit, and since they were privy to those IBM design meetings they knew all kinds of not so generic ways to do that.

It’s all very cool thought.

Legacy VMInit 0003ff00 005720000 <<< but before this one.

Legacy VMInit task is responsible to initialize the BlueBox environment, the emulator were all the 68k code built in these older OS versions runs. MacOS9 still has a lot of 68k code, not only running at high level, but also running at low level, in drivers, extensions and toolbox firmware device managers. That explains why the OS stops very early in the boot process. Is also said that the Bluebox makes use of PPC/MMU rare instructions and chip facilities to speed up the emulation.

Probably QEMU CPU/MMU emulation is still not good enough to run the BlueBox environment. MacBugs uses almost the same facilities that BlueBox. So, if they manage to run MacBugs in QEMU, for sure it will also run Bluebox, allowing the OS to boot full to desktop.

Similar to PearPC, the memory configuration is important. With Puma the virtual memory wont initialize if the guest memory isn’t set to 128, but even then it will stall there with the build I’m using.

I may have had a breakthrough with DP4 but I don’t want to speak too soon. I haven’t even touched GNUStep or MKLinux, but sometimes my heart becomes faint 🙂

To be honest I thought there would be at least twice as many posts on this thread, but I suppose interest in PPC emulation is not what it used to be…

The early Amiga NetBSD installation tools could write directly to the disk, I suspect the same holds true to the Mac? I’ve only installed Net/Open on an OpenFirmware Mac so I could boot from CD.

Then again anything that old would be 68k, and probably wouldn’t support disks the size you’d hope for on a PowerPC.

After that I tried setting the 9.2.2 System folder as the boot, and open-firmware has a good inspection for a few seconds before dumping out to the ‘…no valid state set’. I might be able to get further with some bad magic at open-firmware, but I have a lot to do at the office today.

One last thing, neozeed could you recommend a good PPC program to write a dmg hd image back to a physical drive? In any case I will look into it myself later.
