I have a Powerbook5,7 on the way to me, happy to join in with the MacOS9 tinkering!

Thanks! Amazing you spotted that, that was quite buried in there. I will give this a try hopefully this week, slowly guttering my device tree, starting with some likely culprits. Let's hope we get a happy Mac and no bricked Mac.

@Jubadub did you have any luck with this? I ended up coming back to this a few weeks ago to see if I could disable some devices to allow sleep. I didn't get very far, when trying to disable a lot of the devices OFW would tell me that the devices don't actually exist.

I didn't look into it, in the end. I had one of those "Mac breaks", so to speak. Honestly, I don't see myself coming back to this anytime soon.

But if someone jumped between us right now, and said "oh hey guys, I got it boot!!!", I would INSTANTLY follow all the steps.

Just leaving a note here for future reference if someone wants to do more testing.
I'm downsizing my gear so thought I'd do some testing in the process to see what machines I wanted to keep.

I had a 15" PowerBook 5,4/5,6? (1.5Ghz) and tried to find a workaround for the trackpad problem again.

The older PowerBooks use an ADB keyboard and trackpad, while the newer ones use USB and that's why they're unsupported. OS9 only supported the ADB PowerBook devices.

So when booting into OS9 the trackpad would be completely unresponsive due to lack of drivers.

I compared OFW devices between a PowerBook with an ADB keyboard/trackpad and noted the `compatible: trackpad` property/value was missing from the USB version.

So in OFW I did the following:

Code: [Select]

nvedit

probe-pci

dev usb2/device@1/mouse@1
" trackpad" encode-string " compatible" property
device-end

dev usb2/device@2/mouse@1
" trackpad" encode-string " compatible" property
device-end

nvstore
setenv use-nvramrc? true
reset-all

This gave the trackpad functionality (but very slow tracking) throughout the boot process but something unrelated was causing the system to crash when loading the Finder so I left it at that.

I am hoping this will be useful to someone who wants to dig into this further

@greystash *like* Although I always plug in a mouse on laptops, I cannot use touchpads satisfactorily.

I still look at my dusty PowerBook 5,8 1.67GHz model with a frown. If earlier USB-based models can boot into Mac OS like 5,6, I don't know why 5,8 can't. According to the developer of Windows NT for PowerPC Macs, it is implied that if a system can work with DDR1, then it can also automatically work with DDR2 (actual comment here).

Between 5,6 and 5,8, I don't know what else changed besides DDR RAM, CPU clock, display resolution and the disc slot drive. Yet we can't boot. Is something in the motherboard's ROM/firmware messing it up?

@Jubadub I do have a 5,8 1.67GHz model, I've never really done anything with it but might get some time to look into it in a month or two (I'm in the middle of moving at the moment)
