Hackers who came up with a way of dual-booting Mac OS X and Windows XP on an Intel-based Mac before Apple introduced Boot Camp have now made it possible to add Linux to the mix.

The OnMac.net project has published instructions on how to triple-boot Mac OS X, Windows XP and Linux using Apple's Boot Camp utility.

The procedure has been successfully used to set up a MacBook Pro, but is as yet untested on the iMac and Mac mini models.

The actual process itself is pretty tricky, as it is not possible to boot Linux from Boot Camp. The open source OS would have to be 'chain loaded' from an installed copy of XP using the LILO bootloader.

Although OnMac.net was created earlier this year with the intention of finding a way to boot Windows on an Intel Mac, a quest that was superseded soon after it was completed by Apple's launch of Boot Camp, the site founders are maintaining the site for new projects such as the triple-boot idea.

Full instructions for triple-booting can be found at Triple Boot via BootCamp.
