Booting LInux from external HDD on Eee Pc

Sometimes, it's necessary to be able to boot from external HDD on Laptop eg: Asus Eee Pc 701 or other brands. Most laptops today have more than enough capacity if you just want to browse the Internet, write documents, listen to audios and anything else.
But occassionaly, sometimes we want a little more. The smallest laptop eg the EeePC has at least 4GB, a capacity that was enough to strip down Linux, eg: Fedora.
But if we do so, it will reduce the hard disk capacity. and that's a little bit irritating. As a tricks, you can install Linux Fedora on an external drive instead, and use your fedora from the HDD. With Linux, that's an easy thing.
