2 post install questions

[R One Oh Seven]

I finally managed to install 10.4.6 when I realized that all my problems were caused by a bad dvd burn.

 

I now have 2 other problems.

 

When I installed osx, I set its partition to active and installed the darwin bootloader. When it loads the darwin bootloader, i can choose xp or osx, either works. When I set the xp partition to active and edited boot.ini with chain0 and put the chain0 file on C:, i can select xp but choosing chain0 results in a flashing of the cursor for a second and returning to the menu. I much prefer the ntloader, so is there a way for me to fix this?

 

Other problem:

 

Whenever I start osx, it gives me an error about some audio driver kext not being installed properly and tells me to reinstall it. My sound card is also not detected in the sound control panel, though I know it's compatible. How do I reinstall those drivers?

Get the full name of the audio kext needing repair.

 

Go into Terminal in the Utilites folder and type (for each kext):

 

cd /System/Library/Extensions
sudo find (name-of-kext) -type d -exec /bin/chmod 0755 {} \;
sudo find (name-of-kext) -type f -exec /bin/chmod 0644 {} \;

example: sudo find AppleVIAATA.kext -type d -exec /bin/chmod 0755 {} \;

 

To get sound working, need to know a brand and model of the audio chip - like Realtek 882 or Sigmatel 9200 or Soundmax 1981.

I got the sound working, but no luck with the bootloader. Could someone help me out?
