In reply to neozeed. It's likely trying to read a PROM or OpenFirmware parameter. It's possible to boot a kernel from a third party location like a floppy or HDD, and tell it to start a CD (boot=cdi I think) at the boot prompt. I had it written down and it's probably in the thread on NeXTForums. It would be fairly trivial to use that to get a full system start if we could get the PPC kernel to build. That would likely require building on PPC Rhaspody though.

In reply to a. Well that's very interesting... Maybe it's a common fault in the platform code

On another PPC machine (40p), Artyom saw that elapsed time in AIX 5.1 was not working.
See http://tyom.blogspot.fr/2017/09/whats-time.html for more details
Maybe a more general problem global on all PPC machines?

In reply to Mark.

I was thinking that too, as 0Mhz seemed a bit odd… If I could figure out how to make those blasted CD’s I’d just re-build my own kernel and hard code it to some answer. I guess if I was smart too, I’d just look at the platform code, and point out where it comes up with 0….

(goes and looks)

Ah yes I think the requirement for BootX is because OpenBIOS doesn’t support MachO binaries, but that’s fairly easy to sort out if someone has the time – otherwise it stays on my TODO list…

Once that’s done it just needs someone to figure out why the ADB/USB isn’t working, although given that the OS apparently thinks the CPU frequency is 0MHz it could simply be that the OS timers are getting misconfigured.
