Ta-da!

Things that need to be disabled:

• PMU
• USB
• Extensions (not sure which ones)

Drum roll please!!!!!

[ELN]

Would somebody (looking at you nanopico) please post on how the mini's USB controller differs from a supported G4?

By the way, here's a tbxi. It has too many ugly hacks to count. The one I am proudest of is the binary patch to the NativePowerMgrLib. Close second is the logging code that you will see spamming the NK log as the progress bar moves.

To start from this ROM, you must first copy the 'boot 3' resource inside into your System suitcase. Then you should empty your Extensions folder.

No USB, so you can't actually do much. Working on it.

Than's some 'fancy' work there ELN... AWESOME!!!

Not sure if my issue is the USB, on PB6,8.

I had considered it, as I'm trying to boot from USB.

If I leave Extensions enabled, things bomb out about a min. or so after the Ethernet loads.

Removing all the extensions doesn't get me any further.

Not much shocks me... but this is absolutely crazy

While time marches on... 2018 and still progress being made... "priceless"

@ELN,

It's USB for me.

I used the Mac OS ROM v9.2.1 that comes on the install CD, rather than the "Generic" or "iBook" ROM.

With all extension disabled I was able to get the progress bar to fully load, but as I'm booting from USB the system couldn't mount the drive, so the Finder never launches.

I assume we likely have the same USB device, here's my IOReg:

Too long to post even in a code box, I'll boot Linux and see what lsusb and lspci return.

What happens if you use Timbuktu (or any other remote control software)? That might let you do some useful things with a mini

[darthnVader]

Just picked up a iBook G4, seems to have the same CPU as my PowerBook6,8. Likely the same USB, as is a PowerBook6,7.

I tried booting OS 9 from USB, and it has the same issue and the PB.

This time I installed the OS 9 drivers on the disk, before I installed Tiger, but I didn't setup an OS 9 partition, wishing I had, as trying to boot OS 9 from the HD results in the "Happy Mac" but it never finds the System suitcase.

Any way I can fix that?

My boot command:

Code: [Select]

boot hd:10,\System%20Folder\:tbxi

[ELN]

We're mostly focussed on the mini on this thread. It seems to have much more trouble starting than a PowerBook does.

For your PowerBook, I suggest using iMic's "Generic" Mac OS ROM. Copy the boot 3 resource from the ROM I posted into your Mac OS ROM file *and* the System suitcase. Run this OF line to boot:

Code: [Select]

2000000 encode-int " AAPL,debug" property mac-boot
Then let us know what the last log message is before the crash. Is there another thread somewhere that covers the PowerBook?

[Daniel]

I would suggest trying to set the startup disk with system preferences. I know that tbxis can be loaded from any folder, but I think the System File has to be in a blessed folder. Or maybe you could try moving the system files to the Coreservices OSX folder (after moving BootX somewhere else). That will probably prevent either operating system from booting, but maybe something will work.

[nanopico]

Would somebody (looking at you nanopico) please post on how the mini's USB controller differs from a supported G4?

I'll look, but it really doesn't.
It's the PMU.  It is controlled over USB.
They will be tied together nicely (or not so much).
That is why the both need to be disabled.

PMU99 (supported) is a Mitsubishi M16C/62F microprocessor.  It uses it's own RAM and ROM.  the uPMU in the mini will likely not have the same ROM and thus not the same interface (from a communication/software standpoint) except for very very low level common functions like turn on and turn off. 
Intrepid controls all IO (USB and PMU communication). The USB controller chip and PMU are known for all the supported and other machines.  The communication through Intrepid is obviously slightly different than the straight up Keylargo chip used elsewhere or else the PowerBooks would have much more  functionality.

So details on uPMU and Intrepid are needed.  There is much info availble in the OS X source to help identifiy the difference between Keylargo and Intrepid. I have found nothing directly related to PMU99 or uPMU in the OS X code (it's a lot so it's not exactly fast to go through).  All power IO does appear to be handled by Keylargo or Intrepid.  So those chips definitly have knowledge of communication to the PMU.  Disabling the PMU and USB controller makes intrepid stop using them so it just goes on it's happy little way.

Okay I'm starting to confuse myself.  I'll dig more when I get a chance.

[ELN]

It seems that my forum post last night did not go through. I got USB working on the mini! The USB controller driver had a dependence on the PMU that I worked around. (All as nanopico predicted!)

[mrhappy]

Hey that's awesome!!

[androda]

I think I speak for all of us when I say Thank you for all your work on this!  And What Mac OS ROM can we use to try this ourselves, for extension compatibility testing?

What other repercussions are there for disabling the PMU?  Does the PMU control CPU voltage?  Don't want to burn anything out.

[nanopico]

The PMU controls sleep and such.  On the mini it really doesn't do much more than that.
Breaking it away from USB will primarily mean that if it goes to sleep (if it can at all) it will probably not wake up and will be required to hard restart.  The link between USB and PMU is mostly for controlling device sleep status.

So here is the warning.
There is a possibility that it could cause overheating and possible awkward state that may not be easily be rectified.  Primarily from some devices sleep and some not.

[macStuff]

congrats on your progress

Well ELN, you going to make us beg

We'd be interest to know how to reproduce your hacks.

[ry755]

By the way, here's a tbxi. It has too many ugly hacks to count. The one I am proudest of is the binary patch to the NativePowerMgrLib. Close second is the logging code that you will see spamming the NK log as the progress bar moves.

To start from this ROM, you must first copy the 'boot 3' resource inside into your System suitcase. Then you should empty your Extensions folder.

No USB, so you can't actually do much. Working on it.

This is great, but how do I use it? It won't boot from it, and when I open it in ResEdit, it says there's no resource fork, and I have to create it! I even tried directly downloading it onto my iBook G3, thinking macOS High Sierra was somehow messing it up.

Do I have to package this up somehow?
