Just installed RC2 completly fresh, backuped the data drives before!

I had to fix the Bootloader manually, but that was easy.

(Startupfiletool and other needed tools are on the DVD already, so there is no need to use additional an additional usb drive:
They are located in /usr/standalone/i386)

Works nice.

Thanks for the System Profiler file, roisoft
