after installing OSX several times, trying out patches, fixes and so on .....
The best result i could get was:
Audio working but only Stereo (edited kext)
Network working (using skge.kext)
Firewire working out of the box
USB Working out of the box
Jmicron PATA and SATA working (edited kext)
ATI X1950XTX 512MB , no dual screen, have to use DVI to VGA adapter, QE and CI supportet, resolution 1600x1024
(not native resolution, would be 1680x1050, but was not possible)
This was already a good working mac, but not perfect enough for me, so i was thinking about to stop
Last try with a Nvidia (7900GS) card from a friend:
Put in the card and made a new installation.
Installed Natit for Nvidia and patched the other things (audio, nic ....)
DVI out is working, Dual Head only Mirror mode, power saving not working and my Monitors were recognized correctly !!
Ok this is better than with the ATI Card, but to buy a new Nvidia Card just for a better working mac clone ? NO !
So, the test with the Nvidia Card was interesting but thats it, and i changed my ATI back into the machine.
Bootet up in to OSX without to change somthing.
And Voila, DVI was working and a the resolution was 1024x768 not changeable.
Now, copied the natit_edited kext file into the Extensions folder, cleaned up the system and reboot.
And to my large astonishment, everything is now perfect !!!
Full Dual Head Support, DVI out for both LCD's, powersaving is working, QE and CI support !!! Juppiiiii !!!
I am so Happy now !! Nearly a perfect mac clone !!
mery christmas to all
