It would seem so. I know that removable media drives such as Zip and Jazz drives can selected as the startup device and of course external, fixed media, hard drives can. Remember, the blessed System Folder is necessary but not sufficient. You MUST have the driver for the device installed WITH the System Folder. I don't think external firewire drives can be made bootable. At least not in all configurations. Iomega drives require their own proprietary format utilities. I'd suspect that to be the same situation for all other external, removable media drives. Fixed media drives can be formated with either Apple's utility, Drive Setup, or a third party format utility. -- T.T.
