Apple has released Boot Camp 1.1.1 beta contains many updates and is intended for all new and previous Boot Camp beta users.
Boot Camp 1.1.1 beta includes:
• Support for the latest Intel-based Macintosh computers
• Easier partitioning using presets for popular sizes
• Ability to install Windows XP on any internal disk
• Support for built-in iSight cameras
• Support for built-in microphones

If you previously installed Boot Camp beta, you can easily update to Boot Camp 1.1.1 beta. You don’t need to partition your hard drive again (unless you want to change its size) or reinstall your Macintosh and Windows software or documents, but it’s very important to update the Boot Camp Assistant software, create a new Macintosh Drivers for Windows CD and install the updated software it contains on Windows XP. Complete instructions are provided in the Installation and Setup Guide included with the Boot Camp 1.1.1 beta software.
