It does actually offer some performance boost in certain apps,

I ran XBench b4 and after but didn't see a diff on my MacPro1(2),1.

JMO but I'm enjoying using K64 mode. It does actually offer some performance boost in certain apps, and is giving me serious washed car effect, which is psychological, but still fun ;-)


performance boost in certain apps?
you know that apps still run at 64-bit when booted in 32-bit kernel?

the main profit with 64kernel is probably that you can adress more then 4gb ram to the OS itself.
which it probably never exceeds atm anyway.

So let me get this right (because I am confused about it). It is possible to run a PC non-flashed 6870 in a MacPro 2,1 (32bitEFI) using the aty.init kext BUT there will be no boot screen. Is my understanding correct here? Or is another card required to be installed at the same time?

Back in April the BIG NEWS was that 6870 could be run OOTB in 10.6.6. from new MacBooks. In 10.6.7 there was an iMac update that held it. In 10.6.8 the regular update did this.

No ATY_

No kext fixes, or driver tweaks. Just update to 10.6.8 and install any old 6870 from wherever. No boot screen but when it reached desktop...KA BANG !!!

So...very old news.

Lion does this too.

The use of an EFI64 flash adds boot screen and kills the steam/dvd bug. There is in theory another way to do this with ATY_Init, but I am not sure how that works.

But the point is...Ever since April, it has been possible to use a 6870 in ANY Mac Pro.

С помощью данного рецепта я смог запустить у себя на MacPro 1.2 (1.1) видеокарту GTX470, не прибегая к помощи инжекторов, карты-помощника и перепрошивки биоса. Цена за это - 1 гиг загрузочной партиции Smiley

With the aid of this prescription I could neglect in itself to MacPro 1.2 (1.1) GTX470, without resorting to the help of injectors, card- assistant and flash videobios . Price for this - 1 gig on hdd Smiley

Thank you so much for doing all the legwork to figure out the pieces needed and to write up such a clear description.  I don't have it working on my MacPro2,1 (thanks for that too) because I think my internal RAID is confusing the Chameleon boot loader.  A weekend project is to try and get it working regardless and you've given so much detail that I'm confident I'll figure out an approach.

Install the older Chameleon bootloader, the filename is Chameleon-2.0-RC2-r640.pkg, you can easily find it on the web.

Just curious, why RC2?  Does something break or go wrong with newer versions of the Chameleon installer?

Works also on a MacMini1,1 (files attached). Though there are 2 main issues :

1. Video stuck at 1280x1024 (instead FullHD)
2. No Sound (even with kextunload / kextload)

So, if we cannot use the EFI64 flash on the 6870 card in MacPro 2,1, does anyone know how to use aty_init to kill the Steam/DVD bug?

What we really need is an EFI32 flash for the 6870 but I guess this is an impossibility since there is no official Apple card that has this.

Today I tried to boot to EFI and nothing came of it ... Can not find boot file. Perhaps there is a terminal command?

boo for 2006 Xserves...

Apple have modified the EFI so that it doesn't even support legacy mode!   Angry

i.e. the following bless command:

Code:
xserve:Boot tangles$ sudo bless --folder /Volumes/Boot --file /Volumes/Boot/boot --setBoot --legacy

gives:

Code:
Password:
Legacy mode not supported on this system
xserve:Boot tangles$

I don't think there's any way around this...  Sad and I really wanted a 64bit kernel to take full advantage of ZFS' L2ARC.

Anyone got any ideas? (other than re-soldering in a 64bit EFI)

I'm a big Mac Pro fan, and I own both a 2006 and 2010 Mac Pro. After writing the firmware tools for these systems, I started to feel like the 2006 Mac Pro didn't get much of a boost from the 2007 firmware upgrade, unlike the 2009 upgrade, which unlocked a lot of potential.

In my testing I haven't run into any issues other than the sound, and benchmarking is right where it should be at for a 64 bit kernel. I hope you enjoy the benefits of extending the value of your 2006 or 2007 Mac Pro, or being able to change your system back and forth from the 32 to 64 bit kernel for development purposes.

Thanks again! I am going to try some video cards out once I've completed this hack. Great guide - very easy to follow and understand.

Hold the Alt-Key at reboot. Choose your "normal" System-Partition and it should boot into 32Bit again.

Change Startvolume in the Sys-Prefs.
