Kext not loaded

[hbqpmywn]

Hi,

 

I've installed ATI HD5XXX kext on my hackintosh, but booting in verbose mode I see that my hackintosh try to load the kext but it says that kext could be not loaded. Why?

 

I've tryed this:

and these:

My ATI is HD5470.

 

 

 

I've another problem with the network. I've installer realtek kext, and everything has been detected right, but during the use I've a kernel panic with these:

RTL8169Ethernet

IONetwork Family (2.0)

IOPCFamily

 

I can't understand the reason...my ethernet is really this model, with this kext doesn't works for me?

 

 

 

It's same week that I try to fix everything, and I've see a lot of posts, but I'm not able to resolve these problems.

I see also that a lot of people ask help to make a hackintosh with a Dell N5010, so I ask to some expert user to answer, please. That could be usefull for a lot of people, thanks.

 

 

 

If need more information about, ask me!
