Problems with booting after changing a kext file

[Jordy27]

I just installed iDeneb with OSX 10.5.7 successfully onto my pc, and it booted/ran great! (except with no wifi, sound, etc). To fix this I downloaded several kexts/install scripts for my laptop model, see here.

 

First I tried to get wifi working, so followed the instuctions as per the link above and ran the installer script, but after rebooting, wifi still didn't work, even after running the airport utility. The install changed something in IO8Family.kext, so I thought maybe this wasn't installed properly and dragged this file from /system/library/extensions into kext helper to install it...

 

When trying to reboot it took a few goes, sometimes just hanging at the grey boot screen. So when it finally booted, and I found the kext file not in ../extensions but in a backup folder, I copied the kext file straight into the ../extensions folder (whoops!). Now when I boot, I either get a stuck boot screen, or a kernel panic. I have tried running with -v but F8 doesn't work - I am using windows boot manager which then loads Chameleon, so I'm not sure why I can't use F8.

 

When I run from the iDeneb disk with boot flags, it just loads the OSX installer. When I have the disk in the drive but load OSX from windows boot manager, it (sometimes) boots into OSX fine, other times jut hangs.

 

I can't quite figure this out, how do I get the kext state back to how it was - also, as a side note, what does it mean if a kext is highlighted blue? Or what else am I stupidly doing wrong or have missed, and how do I get F8 when starting up?

 

System specs can be found from the link above.

 

Any help would be much appreciated, thanks!
