Following the onmac.net project's early attempts at getting Windows XP to boot on Intel Macs, Apple has announced Boot Camp (FAQ), its own fully supported solution to the problem. Booting Windows on Intel Macs isn't entirely straightforward, as the machines use Intel's Extensible Firmware Interface instead of a BIOS, which Windows XP doesn't support. The onmac.net project successfully booted the OS on several Intel Macs, but there were still lingering problems, including a lack of drivers and missing functionality. Boot Camp features an easy-to-use installer with a non-destructive partition manager, and lets users burn a driver CD with the missing Windows drivers for their Macs. Once Windows is installed, the user can pick between Windows XP and MacOS X by holding down the option key at startup. The computer maker said its new "Boot Camp" software is available as a download beginning Wednesday. It allows users with a Microsoft Windows XP installation disc to install Windows XP on an Intel-based Mac computer.
