In a recent conversation with an Apple Engineer I was told that (cooling) fan management was a concern with hacks that allow you to boot your Intel Macs with Windows XP. This is especially a concern with Mac Book Pro's. Apple's Mac OS manages the cooling fan in these computers and keeps them from overheating. No Mac OS X no management of the fan and your logic board may fry. Now come news that using Apple's own Boot Camp software may void the warranty on your new Mac. In a recent article [Link] in the on-line MacUser it was said:
According to the Boot Camp release notes that accompany the software: 'SHOULD THE APPLE SOFTWARE PROVE DEFECTIVE, YOU ASSUME THE ENTIRE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION' (Apple's capitals), although it goes on to say that warranties may be protected by local laws.
Intel Mac user beware, you may be using Boot Camp at your own risk!
