Instal xp on firewire external HD

[jerekb]

I am using an iMac and I want to instal xp on an external drive i have that uses firewire. Can this be done and if so how? I want to have it around so i can just plug it in to pc's when i need it.

AFAIK, Bootcamp won't work with external drives. Why not just set aside a small partition for XP?
