Creating a UEFI Rescue DVD

Developing a UEFI rescue DVD containing a set of useful UEFI-related utilities is a personal project that I work on from time to time. I own a number of laptops with UEFI firmware and have encountered a myriad of strange UEFI-related booting issues on these laptops over the last few years.

Firefox 3 comes with a default Search Bar on the top right hand corner containing a number of default search engines including Google. If I type a search term in the Google Search Bar option, Google figures out behind the scenes that I am located in the Philippines, redirects me
