I am embarrassed to ask this question, so please be kind . I am particularly embarrassed to be such a Sims fanatic. Ha ha. I would like to run XP on my MBP for one reason only - to play the Sim2 with all of its expansion packs. Here are the specs of my MBP: Leopard 2.4 GHz Intel Core 2 Due 2 GB 667 MHz DDR2 SDRAM 160 GB Hard Drive I'm planning on upgrading the RAM soon, as well, to 4GB. Now, I am planning on buying a FireWire 800 HD to run XP. Is there a way to boot XP from an external hard drive via Boot Camp? I read a "how to" and they had a very complicated way of doing this. Is it easier now with Leopard? Or more impossible? Is there a better program to use other than Boot Camp? Maybe Parallels? I don't want to take the internal hard drive out. In fact, I wont. So maybe that sabotages the whole thing. I own a copy of XP and that's why I'd like to do it this way. If this wont work, I guess I'll just sell my Sims2 and expansion packs for PC and buy them for Mac. Thanks for any feedback!
