Shanems3 Posted July 15, 2009 Share Posted July 15, 2009 I keep getting PMs on how i did this, Now that ati 4850 is supported, I will be Reinstalling leopard on the machine. I will let you guys know what it takes. I have successfully installed Leopard before, reading all cores, but the video cards i had were not Supported so I abbandoned the rig and went back to windows 7. I will update my progress on it. I should be done by the weekend. Here are the specs Asus z7s WS motherboard xeon 5450 3.0ghz @ 3.7ghz 8GB FB-Dimm Ram 2 Ati 4850 1gb version 2 SSD Hdds 4 250GB storage Hard drives 1 TB Storage backup drive Blu-Ray Rom Sata Dvd Burner Sata Unit is WaterCooled.

Shanems3 Posted July 17, 2009 Author Share Posted July 17, 2009 Installed 10.5.5, just downloaded a 10.5.7 disk, gonna install that one before I tinker Also, if you boot and get a panic, cpus=1 will get you past that panic, but if you disable ACPI APIC support in bios, you will not have to.

Shane I had iDeneb 1.3 installed, and I tried both the 10.5.7 upgrade Disc and a fresh install of iDeneb 1.5.1 several times with different fixes, and none of my tries worked out. The upgrade Disc gave me a kernel panic during boot, the fresh install keeps hanging right after the "using XXXX buffer headers..." message I used the same BIOS settings as for 10.5.5. Besides, there's still only one core working in my machine... Any ideas already?

Shanems3 Posted August 3, 2009 Author Share Posted August 3, 2009 The trick is to get a working install with 1 core , Update to EFI V9, then do DSDT patch to get all the other cores working Or run the modified bios from Kabyl, the modified bios, will give you a BSOD inwindows though...

ampAIR Posted September 14, 2009 Share Posted September 14, 2009 installed 10.5.8 today, and almost everything worked right out of the box. the first thing was, that there were no audio devices avasilable in the preferences, which i could resolve with the AppleHDA.kext from this thread. the second issue is driving me crazy. as long as i have both monitors connected, i suffer from the already known jumping/lagging mouse & keyboard issue. but as soon as i disconnect one of the monitors, the other one also goes into standby, with osx giving some kind of error sound. this is really annoying, since i can forget about any kind of precise working in photoshop or final cut anybody else experienced that kind of behaviour? sebastian btw: rebooting with one monitor doesn't resolve the problem...
