How to install Mac OS X (Tiger) on Fujitsu U810
Pocketables Forum member technogeekchris has been enjoying his triple-booting Fujitsu LifeBook U810 for a few weeks now and has just posted a great tutorial on how to install Mac OS X 10.4 on the otherwise Vista-running mini notebook. The directions aren’t specific to the U810, but that’s what he’s got it working on with almost 100% success (wi-fi is the current sticking point).
All you need to get an Apple UMPC (of sorts) is a Windows machine, both a licensed copy and hacked image file of OS X 10.4, DVD drive, and "a lot of patience."
Thanks, technogeekchris!
