Hardcore users: What makes it impossible to boot into OS 9 on the 12" Powerbooks? Firmware? Or is it a tag like that prevents the Startup disk from not recognizing the blessed OS 9 folder. The original iTunes was a program that would run in 8.6, but a tag was added to not allow it to run in 8.6. They did this to push OS 9 and force migration from 8.6. I am going to experiment with several hacks. Any suggestions? I really want this thing to run in 9 and will need as much help as possible. Plus, it's a nostalgia thing. I am very serious about this project and plan working on it as long as it takes.

I can't think of any way that Apple has managed to prevent OS 9 booting.
Does the startup disk option in system prefrences still alow you to choose your OS 9 system folder? /forums/ubbthreads/images/graemlins/confused.gif

Easy. They build a motherboard with new features but don't write OS9 drivers for those features. Things like Firewire 800, and Airport Extreme. The System tries to boot into OS9 and, with nothing to help it cope with those ports, it goes PBBBT!
This is why the new iMacs and such still support OS9. They don't have those features.

My 667 DVI sometimes seems to have problems with OSX on the net. This began after upgrading to 10.2.3 I think. Paying bills leaves me with an encryption error message to my horror; I don't know whether the bill has been payed or not. I switch to OS 9.2 and everything goes thru no problemo. Makes me lean toward the Ti Ghz as my next Ti. Basically I feel the Powerbook series has always had weak modems; from past experience of trying to use dialup in motels; the Ti would not work but my PC laptop would never miss a beat getting connected. Just my obvservation.

The 15" new tibook will still boot 9. Does this mean it doesn't have firewire 800 and the like?

I don't know what to correct first. /forums/ubbthreads/images/graemlins/tongue.gif
There is no "new" 15" Powerbook right now. In the last revision when the 12" and 17" were introduced, the 15" had a price reduction I believe. Maybe the factory-equipped RAM and HD capacities changed. But the machine itself is the same as before. Non-Extreme Airport and Original Firewire, too. As you can see from the comparison specs sheet on Apple's web site.
That Powerbook is due to be updated in the near future. It will have an aluminum enclosure and the screen will be 15.4". It will also have Airport Extreme and the new Firewire 800 (and that dumb GForce4 440 Go graphics card). So what you're calling the "new 15" tibook" will be neither 15" or Titanium. /forums/ubbthreads/images/graemlins/crazy.gif
Exact dates for the new Powerbook are unknown, as Apple has to get stock of the OLD 15" TiBook cleared out first.
And to answer the real question, I gaurantee you it wont boot into OS9.

I'm under the impression that the new Al PBs have had their Firmware doctored to prevent OS 9 booting - but that being said, I came acroos a site/forum with link that showed an easy circumnavigation on PMs (iThink). I'll be damned if I can remember where though. If I do, I'll repost.

Nah. If there aren't any OS 9 drivers for the PowerBook, it won't boot in OS 9, period. Updating the firmware would just be overkill.
One question, though:
If there aren't any PowerBook drivers for Mac OS 9, how is it that Classic can boot? Does Classic provide its own ROM file?

Remember, Classic is an emulation of 9. It runs in Blue Box (boy, there's a term we haven't heard for awhile) on top of Darwin as a program. When you're working in Classic, printing tasks, ect are passed off to OSX to send along. This explains lots of the problems with internet and printing in OSX's early days while using Classic. Since OS9 isn't interfacing directly with the ports in Classic the driver thing doesn't apply.
At least that's how I understand it.

[dcipjr]

Yeah, Blue Box. Forgot about that. The Classic environment supplies its own ROMs.
Check the OS 9 version of Apple System Profiler when you're running Classic. It says Blue Box.
And if I try to open the copy of Bugdom that was bundled with my Mac using OS X, it'll tell me that I'm not using an iMac, which it requires. Not like it would run anyway, since it uses QuickDraw 3D.
I don't believe Classic is emulation. It's a compatibility layer, similar to WINE for Intel-based Linux systems. Emulation would be way too slow.
