I got XP running on the AMD 2.5ghz Mini. Took some trial and error and some manually installed drivers from the Win 7 CD that boot camp burns and some drivers from an older 2010 Mini OS CD. I got internet/ethernet working. No sounds, wireless or good graphix driver. I tried the latest AMD Catalyst all-in-one driver but its not running. Can only get slooooow 1600x1200 video on my Cinema HD. Anyone found a driver for the AMD graphix card on Win XP? PS: A tip for anyone trying to install XP on the new Mini using an External Superdrive: depending on the installation CD you will have, the installer will ask you to locate a few files after rebooting during install. The proper path for all of those files is "H:\I386" might be a different letter for your superdrive but the directory is X:\i386.
