Has anyone tried or heard of any success in installing Vista (or XP) on an external drive hooked up via eSATA as opposed to USB or FireWire? Can a MacBook Pro even boot a volume hooked up this way via the ExpressCard slot? Any experiences or knowledge to the matter would be appreciated. I'm trying to figure out what setup to take for Vista/XP games and I'd prefer to use a large external drive. I think I may end up going with a small internal partition and then use the external drive for data, but even still I think I'd prefer to keep Windows in it's own environment completely if possible.
