NT on PowerPC Macs!

Rairii said:
Today I got bored and decided to see how long it'd take me to get to setupldr on uni-north (with the powerpc in little endian mode)

...three hours, and most of that was debugging the PMU/ADB code, which has an off by one error (yet somehow works on Lombard, probably different PMU firmware?)

Thank you! This is great to see. I'd love to get NT working on some of my other Macs. Right now my B&W G4 is the only one I own that's supported (I don't count the iMacs as I don't have the skill to add an ADB port to them).

I have so many PowerBooks I get bored with just Tiger and Leopard installed on them😄

a *lot* it lays the groundwork for every G3 and G4 Mac going forwards to the very end, so its quite exciting to see :)

since after the initial round of new world Grackle machines, every G3 and G4 was some form of Uninorth based :) there was Uninorth 1 (Clamshell, Pismo, first TiBooks, slot loading iMacs, Sawtooth, Cube and GigE) uninorth 1.5 (later TiBooks the DA/QS) Uninorth 2 (MDD/Xserve) all used with varying versions/revisions of the keyLargo south bridge, and then there was Pangea and Intrepid/Intrepid2 which where all in one Uninorth+keylargo rolled into one ASIC for portables/consumer machines, Pandgea was first, PC SDRAM based, used on snow iBook G3's early eMacs and iMac G4's, Intrepid was DDR based used on all the AlBook G4's Mac Mini, later eMac's and iMac G4's etc, Intrepid2 is DDR2 based, only used on the DLSDs

Presumably this would exclude the 2005 iBooks/Powerbooks as those have their keyboard and trackpad connected via USB rather than ADB. Not sure how much extra work USB is going to take from where it is now, at least for peripherals if not storage.

yeah, in the current ADB only state those would be excluded, but this at least lays the groundwork for those, so when USB is working, those should work when Uninorth is working :)

Which uni-North models use ADB internally? G3 iBook, and Pismo/Titanium PowerBooks?

try using the latest test build, it has PCI-related fixes

It was looking hopeful with my DEC 21140 card, but after running through installation and restarting the card fails to start.

I should probably verify the card does actually work as I got it off eBay. Edit: yes it does under OS X.

So close!

Hah.

I did the update and the network card still doesn’t work, unfortunately.

I wonder if there is an actual driver in there. The system might be able to probe the card and return the IDs but maybe no further. What card did IBM use in its RS/6000 systems?

I think it has drivers for the cards it lists. Did anyone else try?

Is there any news on development?
I'm really looking forward to support for ibook g3 snow.

I was actually about to comment the same thing. It looks like the dev did have some activity last week on the github though, regarding untested Nvidia support.
No activity on the uninorth port or anything else has shown up in issues or anything else in over two months though.

I was happy to see the activity on the Nvidia thing, just so we know it didn't get abandoned.
