Hello artur,
I find time at last to try to solve my problems.
Here's is my ioreg https://dl.dropboxusercontent.com/u/24743784/hackintosh/iMac.ioreg
Here's is dsdt I used on main hard drive with 10.9.5 https://dl.dropboxusercontent.com/u/24743784/hackintosh/DSDT.aml
With this dsdt my display goes to sleep, but system continues to operate most times after Apple logo screen when system starts.
I tried to create my own DSDT trying to solve this issue. Here it is https://dl.dropboxusercontent.com/u/24743784/hackintosh/DSDT%202.aml
With it display works, but I just see my desktop for some seconds after login screen and computer restarts before dock appears.
Help me, please. What's wrong with these staff?
