Modified RockHopper2 ATI drivers for Mac Mini( OS 9 ).

[darthnVader]

These drivers are pretty buggy, but they work for 2D/3D.

I did not include the ATI Video Accelerator, as it hangs the system and requires to force quit.

I tested Rave with Unreal Tournament, and OpenGL with Quake 3.

Quake 3 did crash the system at higher screen res.

YMMV, these are pre-alfa drivers. I haven't done a lot of testing, and sometimes the 2D accelerator may hang when it loads at boot.



 

[MacOS Plus]

  Thanks for that, I'll try it out.  I have three additional ATI files present that weren't part of your set nor mentioned:

- ATI Driver Update 2.4.4
- ATI MPP Manager 1.2
- ATI ROM Xtender 1.2

  Do you have these installed also unmodified?  Do I even need any of these present?

[MacOS Plus]

  So this is certainly a big improvement, especially having functional acceleration.  As it stands, I would have immediate applications for this machine even with the remaining bugs.  It's nice to see a nearly correct set of resolutions offered, although I can't use 1920x1080 60Hz properly because something is wrong with the timing tables.  On VGA the image is the wrong width and shifted quite a bit to the right.  My LCD can't adjust enough to compensate fully.  I'm going with 1280x960 75Hz for now to keep the image centered and proportional.

[ELN]

Great work!

I suggest https://github.com/elliotnunn/patchpef for editing PEFs. And dig up a copy of MacNosy if you want a very sophisticated interactive disassembler.

[ELN]

2D acceleration works for me. I can select between three sensible-looking resolutions for my cheap Asus LCD.

Fantastic!

[darthnVader]

Turns out that the trouble with Quake 3 was it not finding any sound device. Now that we have sound working on external power speakers, it works great.

Does anyone know of a full list of OpenGL/Rave games for OS 9?

Also any links to where I might find some of these games:

MOHAA
MOHAA:Spearhead
JKII

Also, if anyone is running OS 9 on an iBook G4 with Radeon 9200 graphics, I can likely get 2d/3d working on those too. Just need to know the Device ID of your 9200.

  That's really awesome about OS 8.6.  I had actually posted here a while back asking about the possibility of making it work on later machines, but the discussion didn't go anywhere.  I have a very specific thing I need that for.  It would be terrific if you could post exactly what you modded to make it work, and then I can try to replicate it myself.  I have a perfect MDD doing nothing right now that I could use for the task.

It was just a matter of replacing the Device ID's for the Radeon 9200 Mac Edition with the one for the 9200 in the Mini.

I've got an iBook with 9200 on it's way to me, so I'll be hacking the drivers for the Via soon, and I'll post them if I can get them working.

For the Mimi we had to use the 'NDRV' from 10.3.7, later 'NDRV' didn't work with OS 9, tho for my iBook G4 with Radeon 9550 the 'NDRV' from 10.5.8 works just fine.

The Mini seems to have trouble with 1920x1080, and I've not been able to figure that out yet.

Nice work getting 8.6 going, I gave it a try in Qemu, but it bombed out during the ROM load with the Mac OS ROM for the Sawtooth. Never thought of trying to boot it native, but I don't think I have any software that would run under 8.6 that won't run under 9.2.2.

I always found 9.2.2 to be more stable, years ago with testing on my 8600. I had 8.5 Retail CD, and updated to 8.6, but I wanted to use iTools, however it required OS 9, and OS 9 was selling for more money than I wanted to give, so I hacked the 9.1 update to do a full install of 9.1 over an 8.6 install rather than 9.0.

9.1 was very unstable with my Sonnet G3 in the 8600, so I figured I'd try 9.2. I didn't use the OS 9 Helper, I hacked the system myself with resedit via info from an old thread that is now gone from the internet. I made a few custom changes to 9.2.2 and it was rock solid for me.

Thinking things on the internet would last forever, and having a backup of my modified System Suitcase, I posted the changes I made back the the forum I read to learn how to hack it.


OS 9 Helper doesn't make the correct changes, it will boot and work, but I always found it highly unstable, my hacked system worked much better, but my backup on CD suffered from Bit rot, and the forum with the info I posted is now gone, so one day I'll have to recreate what I did.

[darthnVader]

BTW, the Quake 3 crashes I was having were do to there being no sound device. Now that we have sound on the Mini it's been 100% stable for me with 2d/3d.

The trouble I was having with system freeze at boot, when loading the ATI 2d accelerator seemed to be linked to the ATI Video accelerator, using a later version seems to work just fine. However, the last thing I've been unable to check is DVD playback under OS 9.

The OS 9 DVD player says the Mini is unsupported and quits, even tho ELN made the Mac OS ROM report the system is a G4 Cube.

So we have to figure out what DVD Player is looking for, so we can test Hardware accelerated MPEG2 playback with these drivers.

I don't remember, was there a MPEG2 extension, or Plugin for Quicktime on OS 9?

 

[LightBulbFun]

Cool good to know have you enabled any other ATI cards this way?

indeed sadly the Sawtooth 8.6 image causes QEMU to crash...

thats pretty cool on the 8600 front id very much be up for hearing how you got 9.2.2 on there exactly, I have a 4400/160 which is not supported by OS 9 helper and as such cant run 9.2.2 sadly... it would be cool if i can get it running 9.2.2 by manually patching it My Kanga Runs 9.2.2 very well via OS 9 helper tho (and Mac OS X 10.2.8 via xpostfacto)

 its funny I have gotten the 4400 to run Mac OS X 10.2.8 but not Mac OS 9.2.2  https://forums.macrumors.com/threads/success-with-the-power-macintosh-4400.2077767/

PS why does ELN make the ROM change the Compatibility and Model properties to PowerMac5,1? I would personally just leave it be as PowerMac10,1... but im curious why he changes it to that of the Cube?

PS why does ELN make the ROM change the Compatibility and Model properties to PowerMac5,1? I would personally just leave it be as PowerMac10,1... but im curious why he changes it to that of the Cube?

  The issue that arose on my Mini at random, and presumably would have on everyone else's eventually, was that OS 9 believed the Mini was an iBook and would automatically shut down to protect itself when it erroneously 'detected' the presence of a depleted battery and thinking it was running only on battery.  This may have been partially related to the hacked handling of the PMU, which was required to get this machine going in the first place, but as it stood would have made further testing next to impossible.  The simplest fix for now was to force the machine model to be detected as a non-portable type, which ELN selected to be the Cube as cute and mildly appropriate designation - it's the most similar 'flavor' of machine type/packaging, you might say a 'baby cube'/'son of a cube'/cube junior'.

  When the underlying issues get figured out, sure, it would be lovely to have the OS display a proper identity for the PowerMac10,1.  That would likely require more complex changes to prevent the 'portable phantom battery' behavior from happening, but for now we're served sufficiently well with the "Cube" designation for the sake of working through the rest of the major fixes we need to accomplish (minor remaining video bugs, correct sound device handling in control panel, better PMU support).  To some extent the Mini is a learning exercise that will help with compatibility fixes on other machines too, so the more stable a test bed right now, the better.

[darthnVader]

Cool good to know have you enabled any other ATI cards this way?

I modified the drivers for the 9550 device ID, the ATI Graphic Accelerator doesn't load, but the system reports 3D Rave and OpenGL to apps, however Rave games just freeze while testing for 3D, and OpenGL games go to a black screen.

I was hoping the R3xx and RV3xx would work in some sort of backward compatibility mode, but thats just not the case, ATI must have changes the way the registers are mapped from R2xx to R3xx.

No great loss, tho having a fully accelerated  9800 under OS 9 would be so cool, it just wasn't to be.

[macStuff]

having a fully accelerated  9800 under OS 9 would be so cool, it just wasn't to be.

are u saying we would need to find whoever worked for ATI and employ them for a few weeks to get this done?
that sucks :/

Hi LightBulbFun. Great work on getting 8.6 to boot on unsupported hardware! I have been able to replicate your work up to a blinking "?" on a floppy, but couldn't quite be bothered moving my hard drive to the KeyLargo bus.

Your work got me thinking about how I could adapt my build system to older Mac OS ROM versions. I have branched my newworld-rom repo to produce ROMs that are functionally identical to the Sawtooth 2.5.1 ROM: https://github.com/elliotnunn/newworld-rom/tree/version-2.5.1. The binary diffs are pretty clean.

Cool, shame the R/RV3xx cards dont work with the drivers, for gits and shiggles it would be fun to try the same sort of patch with/for something like a Flashed FireGL X3 (I have a picture somewhere of that card running in OS 8.6 flashed to an X850 XT no drivers of course tho, you check out how I flashed the X850 XT ROM to the FireGL X3 here here https://forums.macrumors.com/threads/eeprom-replacement-and-flashing-x850-xt-rom-on-firegl-x3.2016538/

@ELN

Thanks! im glad its working on your machine, Just wondering whats the specs of your machine exactly?

For the record I have also been able to Boot Mac OS 8.1 on a Rev A G3 BW by using the Mac OS 1.2 ROM from 8.5.1. sadly it freezes during extension load but boots up fine (and very quickly) in safe mode, iv not been able to track down which extension is causing it to lock up tho.

It's a FW800 MDD that I flashed with the FW400 ROM.

darthnVader, I've been having a peek inside some of these ATI binaries and I notice that a lot of them have debug symbols, perfect for patchpef. Could you furnish us with a write-up on the function of each file and the exact patches required?

Got round to trying Mac OS 9.2.2 on my Mac mini (with Darthnvarders drivers)

can confirm it boots fine on my end I had a quick game of Quake 3 and it ran very well at max settings, I have to say while as an OS X box the Mac mini G4 aint the best, as an OS 9 Box it runs VERY nicely, I just need an SSD and this should be off its tits quick in 9 

only "Major" issue is Just as finder loads Monitor goes to sleep mode when connected via DVI, works fine via VGA tho. (I only sadly 1680x1050 via VGA but thats a Quirk between my monitor and Mac OS 9.2.2 in general with all systems, so working DVI would be nice)

I too would be interested in a write-up on how to patch the extentions with the Device IDs etc (Id like to test my iBook G4 Radeon Mobility 9200 with the same patches, and I know someone with an 1.25 eMac with Radeon 9200 I might be able to rope in for testing )

in OS X adding device IDs to drivers is easy just add it to the relevant place in the info.plist file LOL!

That image is hilarious, the "G4 Cube" running at 1666 Mhz... this is getting too fun... going on ebay to buy a Mini... sold at least 4 for peanuts ($75) is 2014, may I can buy them back

I was going to wait for Internal Audio Support, but Time to get a FW interface out
