p2pnetMacIntels can be booted with both Apple and Microsoft operating systems.
But now there's news of something completely different ------ OnMac is touting Boot Camp with Linux ; )
It's been used to set up a Macbook, "but is untested on the imac/mini," says the site. "Therefore if you try this you do so at your own risk."
It also notes ominously, " this procedure can potentally [sic] Destroy all data on you machine's hard disk drive, so make a backup first".
If that hasn't put you off, it can only be because you're interested for educational purposes. Right? heh.
Anyway, you'll need one or two items, namely: an Intel Mac, of course; OSX install DVD(s); a non-upgrade windows XP cd with SP2 slipstreamed; an x86 linux live CD/DVD (perhaps the gentoo 2006.0 live CD); the Intel Mac firmware update (early 2006 models only); Apple Boot Camp; and, the OSX 10.4.6 combo update.
Triple Boot via BootCamp.
Triple booting OS
I'm sure eventually the linux open source community will figure away to just install a Linux on a Mac, I bet Steve Jobs didn't see that coming eh a Linux OS on a Mac.
