Jaguar on newer hardware

Hello,

thought I'd post my experience trying to run Jaguar on three Macs that originally shipped with 10.3.x. I've got a few questions as well, perhaps someone can help me out. First, why Jaguar? Two reasons actually: It was the first version of Mac OS X I ever used and I do kinda prefer its look and feel to the somewhat more subdued look introduced with Panther. The Jaguar partition I deployed was set up in Mac-on-Linux and fully updated before booting it on these systems.

12" PowerBook G4/1.5 (2005) | Model: PowerBook6,8 | Official minimum OS: 10.3.7

Working in 10.2.8

- Keyboard
- NVidia GeForce FX Go5200: colour depth/resolution switching, Quartz Extreme, dual display support
- Display brightness adjustment on internal display and an ADC Cinema Display using slider in Monitors pref. pane and function keys
- USB (at 1.1 speeds): a mouse works
- FireWire: recognised in System Profiler
- AirPort Extreme: can see available networks
- Bluetooth: pairing with mobile phone works
- Ethernet: recognised in System Profiler/Network pref. pane
- Modem: recognised in Network pref. pane
- CD/DVD reading
- Battery charging and monitoring

Not Working in 10.2.8

- Trackpad (the 2005 PowerBooks dropped the ADB keyboard and trackpad for USB ones)
- CPU clock speed scaling: it's always running at full speed
- Sound
- Sleep
- Clamshell mode with only an external display being active: System freezes at the login window when I boot with the lid closed or close it while it's running
- Disc burning in Finder: "not supported" in System Profiler

Given that the 867 MHz and 1 GHz versions of the 12" PowerBook shipped with Jaguar, these results might not be very surprising because the 1.5 GHz model has the same GPU, for instance.


12" iBook G4/800 (2003) | Model: PowerBook6,3 | Official minimum OS: 10.3

Working in 10.2.8

- Keyboard
- Trackpad
- ATI Mobility Radeon 9200: colour depth/resolution switching, Quartz Extreme (dual display support not enabled/tested yet)
- Display brightness adjustment using slider in Monitors pref. pane and function keys
- USB (at 1.1 speeds): a mouse works
- FireWire: recognised in System Profiler
- AirPort Extreme: can see available networks
- Ethernet: recognised in System Profiler/Network pref. pane
- Modem: recognised in Network pref. pane
- CD/DVD reading
- Disc burning in Finder fully supported in System Profiler
- Battery charging and monitoring
- Sleep
- Sound including volume adjustment using function keys

Not Working in 10.2.8

- CPU clock speed scaling: it's always running at full speed

I am surprised that this machine works so well in Jaguar, especially the mobile 9200 which was not available in any Mac that came with Jaguar. (I know that the Radeon 9200 Mac Edition has drivers for 10.2.8. I did not install them. The original ATIRadeon8500.kext v1.2.26 is used.)


Mac mini G4/1.42 (2005) | Model: PowerMac10,2 | Official minimum OS: 10.3.7

Working in 10.2.8

- USB (at 1.1 speeds): keyboard and mouse work
- FireWire: recognised in System Profiler
- Bluetooth: pairing with mobile phone works
- Ethernet: recognised in System Profiler/Network pref. pane
- Modem: recognised in Network pref. pane
- CD/DVD reading

Not Working in 10.2.8

- ATI Radeon 9200: no colour depth/resolution switching, no Quartz Extreme
- Brightness adjustment on an ADC Cinema Display
- AirPort Extreme
- Sound
- Sleep
- Disc burning in Finder: "not supported" in System Profiler

I was surprised that Jaguar boots at all on a Mac mini but it has several limitations impacting its usability. At least it retains the colour depth and screen resolution set in a supported version of Mac OS X so for me the graphics department basically boils down to having no acceleration/Quartz Extreme. I have tried adding the 9200's device ID (0x59621002) to 10.2.8's version of ATIRadeon8500.kext which results in the extension being loaded but the status quo doesn't change, I still can't adjust colour depth or resolution, it still reports an "Unknown Display" and Quartz Extreme is disabled. The mid-2004 drivers for the 9200 Mac Edition install a newer version of this extension so I also tried adding the device ID to that but the result is the same as with the original version of the kext.

I'm a bit stumped as to why the desktop version of the 9200 in the mini is not taken to by Jaguar even after adding its device ID so the correct kernel extension is loaded whereas the mobile 9200 in the iBook works perfectly out of the box (without any modification to the kext) despite both being not officially supported by Jaguar. A thought occurred to me: it is possible that the iBook G4 ran Jaguar while it was being developed.

Does anyone have a pointer how I might persuade the mini's desktop 9200 to work in Jaguar? My experience with the iBook and the availability of 10.2 drivers for the 9200 Mac Edition suggest it may be possible. smile

Re: Jaguar on newer hardware

The 9200 on the mini is just connected with AGP (just no slot), so you could try the Mac Edition drivers. They might even work.

I like Jag for those systems that are primarily running Classic apps, or need legacy EtherTalk connections for AFP. I still run it on a strawberry iMac.

I tried them and added the device ID to the new ATIRadeon8500.kext but it didn't work. The kext was loaded but the situation didn't change.

Re: Jaguar on newer hardware

I've purchased some 10.2 install disks, want to give this a try on my 1.25 G4 Mini.

I'll try a few different drivers and I'll report.
