Hello!

I have problems with two things on my A8N-E FM/S (nForce 4): The Bootloader isn't activated, it doesn't boot after the installation. If I'm booting using eith the DVD, the X1600 drivers seem not to be installed properly, I get no CI/QE.
Why are you still using Version 1.1 of ApplePS2Controller.kext? V2.0 was working without problems.
Interesting: The 10.5.1 Rev. 2 DVD wasn't booting on my old Toshiba ODD-DVD1802M drive, but the 10.5.2 is. They're using the same media type, Emtec DVD-R.

Off-Topic: Try using Xslimmer. It can reduce your files enormous. iChat is reduced from 110MB to about 17MB.

ah thanks for that I will take a look @ Xslimmer !

Be very careful with Xslimmer as many programs dont like it and will stop functioning completely.

Xslimmer uses a blacklist for programs which make problems, it worked always flawlessly on my system. And you can backup your original files.
