Hi,
it is hard to describe my problem - after update my OS from 10.6.6 retail to 10.6.8 I cannot use my system, because I don't see my desktop :/ I only see some black squares (take look at photo). No errors when I start my system with -v

My PC:

CPU: Intel Core 2 Duo E6300
RAM : 4x1GB Kingston 667 MHz
Mouse and keyboard use usb;
GPU: evga eGforce 9800gtx+ (Newest chamelon with pciroot =1)
1 HDD on Sata

Hi, I have the same problem with the hardware described in the firm. I made the update from 10.6.7 with the combo 10.6.8 and installed the legacy kernel 10.6.8. Could you explain me what I have to do: what is npci=0x2000?
Thank you
Andrea

You should add kernel boot flag npci=0×2000 to com.apple.boot.plist, or, in my opinion, firstly try to start system with this flag - you simply write npcci=0x2000 on chamelon boot screen, then if everything is ok, you add this parameter to com.apple.boot.plist

Great, It works .
Now I have to insert the kernel boot flag npci=0×2000 in the com.apple.boot.plist.
I would like to know what means this flag.
Thank you again.
