Fix TimeMachine on OSX86

If your TimeMachine stops working on an OSX86 machine, this is most probably due to IONetworkingFamily.kext, located in /System/Library/Extensions/.

Just replace your current one with an older backup (from TimeMachine backup folder) using OSX86Tools. Using the same application you also can make occasionally (especially before making major updates to 10.5.x) a backup of your Kernel-Extensions.

Fix ALC889A sound for OSX86 after 10.5.5 update

Use OSX86Tools or Kext Helper to install only AppleHDA.kext from 889a.Audio.ICH10.zip, which can be downloaded from this forum post.

ATI Radeon HD 3850 on OSX86 10.5.5 (with sleep)

I finally managed to get my Asus ATI Radeon HD 3850 (EAH3850 Smart OC 1024 MB) to work with OSX86 10.5.5 using the following driver from lastExcile / Netkas (see also forum entry on InsanelyMac). Even sleep and wake-up works perfectly, which didn't work at all with my previous Sapphire ATI Radeon HD 3650 graphics card. The card is very silent and Aperture finally rocks (compared to Geforce 7300 GT 256 MB). Trying now another Asus ATI Radeon HD 3650 on another machine if sleep might work with a different motherboard.

Path to com.apple.Boot.plist

The file responsible for startup configuration
     com.apple.Boot.plist
can be found at
     /Library/Preferences/SystemConfiguration/.

It is always good to make a backup of that file if "something" goes wrong.
