NPPraxis Posted May 3, 2008 Share Posted May 3, 2008 Hi guys, I'm a Mac enthusiast at home and a Windows desktop support analyst at work. I generally have a high technical aptitude, but in the case of the Macs have never had to deal with stuff like kexts (obviously, because a store-bought Mac "just works"). I've always bought Apple laptops, and I finally bit the bullet and built me a Hackintosh. Core 2 Quad Q6600 (2.4 GHz), 4 GB of RAM, Geforce 8800GT, 500 GB hard drive + extra 160 GB drive for Vista installation, camera, DVD-RW, HD-DVD drive (got it for $20)...I love it. It's my first new desktop in five years, and it's the snappiest machine I've ever used (store Mac Pros always have 1 GB of RAM). I have an Asus P5W Deluxe motherboard. I installed using Kalyway 10.5.2, and chose the Vanilla kernel, the version of NVInject that said that it was best for graphics cards with 256 MB of RAM, and I picked the right Ethernet driver so that works fine. However, I must have missed the checkbox for the correct audio driver, as I have no sound and System Profiler detects no onboard audio device. I googled and found a download called p5w-dh_sound_net_leopard. Like I said, I've never dealt with Kexts before so I hope I'm doing this right. I tossed ALCinject.kext and AppleHDA.kext into the System/Library/Extensions folder, then repaired permissions and rebooted. After reboot, I get an error dialog about ALCinject.kext, and everything works exactly as before (no sound). What am I doing wrong? Thanks! One other thing- I get an error about unknown CPU when I boot and About This Mac just says 2.4 GHz Unknown. I figure this is due to an outdated BIOS. On the Lenovo machines at work, we update the BIOS through an installer on Windows. Obviously, this won't work here. I found the latest BIOS .ROM file on Asus' website, but how do I install it? Note that I have no floppy drive, but I do have a thumb drive. Thanks again!

kday Posted May 5, 2008 Share Posted May 5, 2008 Go to the terminal and type these commands: cd /System/Library/Extensions sudo chown -R root:wheel ALCinject.kext sudo chmod -R 755 ALCinject.kext sudo chown -R root:wheel AppleHDA.kext sudo chmod -R 755 AppleHDA.kext sudo kextcache -k . (don't forget the dot) sudo rm ../Extensions.* After you do this, just repair permissions, and reboot.
