Because I've got a bunch of stickie threads in this forum, it's pretty cluttered, so I'm going to start moving stuff from the existing stickies to this one. Take that as a warning that things will look different soon!
I'll try to do things one issue at a time, and I will NOT do anything to the "Official Boot Camp Experiences Thread" (in part because it's too darn big!).
OPTIONS FOR RUNNING SOME OS OTHER THAN MAC OS ON YOUR MAC:
> Starting out, a PowerPC Mac can use VirtualPC, a Microsoft product that is no longer produced/supported. It works, though it's slow, and it's an emulator, so some hardware may not work properly or at all.
> Intel Mac users can use Parallels, another emulator produced by the guys who invented Virtual PC (before MS bought it). All reports say that Parallels is fairly quick and it works for almost everything. Some notes though: if you want to run Windows for games, forget Parallels-Parallels works fine but games often don't "play nice" on Windows, so you're in for trouble if you try games under Parallels.
> Both of these emulators should be able to run appropriate distributions of Linux, and Parallels has been improved to do so fairly well by all reports.
> Boot Camp is Apple's "dual boot" product for Intel Macs. It configures your hard drive to accept a second operating system by taking a factory original, single HFS+ partition, reducing the size of that partition and creating a second partition that Windows can format in its own way. It also lets you burn a CD of Windows XP drivers for your Mac hardware.
> BOOT CAMP'S DRIVERS ONLY WORK WITH WINDOWS XP-SP2, SO YOU NEED THAT VERSION. It's easy to combine the free SP2 update with a factory XP disc that is of a previous version (it's still gotta be XP!) through a process called "slipstreaming." There are a bunch of tools to do this, including a command line tool that comes WITH the SP2 upgrade.
