Hello Again, I am writing from my new fully functional hackintosh
I think that one of the issues was chrome, I've followed your guide without installing anything before I managed to boot it from hard drive. Funny thing is. After the update went well and clean and I had a bootable 10.6.8 it no longer used the native graphics controller on my mainboard.
I connected the monitor directly to the Graphics card GT 240 it went smooth.
I've installed it on ssd 60Gb so boot time is insane !
The only thing I am not sure is working is ethernet socket, it looks like undefined in system preferences. It's not an issue for me because I've got working airport already but just letting you know.
Overall working fast and great. With nVidia drivers I am able to manage my resolution in settings although I do get a blue screen after I choose one (like it applied it instantly) but after quick reboot it's all good.
Other than that nothing much to report, all of the software that I need is working perfectly fine. So I guess your dsdt can be safely included in the tonymacx86's spectrum of working devices.
It's a great way to get a cheap mac as well since mine with 8Gb of memory and a second hand GT 240 1Gb graphics cost me only 480$ - That's including SSD and all the accessories - bluetooth, wifi, keyboard and mouse - all except from the monitor.
Anyways I wanted to thank you a lot again. Keep the community alive.
