BoredStiff writes "Tom's Hardware has a review of the Bart PE Builder software utility takes Windows XP and shrinks the OS to your USB flash drive. Besides converting your mini-drive into an emergency boot disk, you can use the utility to load a Web browser, media burning software and more - to have handy anywhere you go. And by the way, it doesn't violate the Windows XP EULA." From the article: "If your PC has a relatively new motherboard, its BIOS will already include the functions necessary to support USB-attached boot media. If so, you need only make the right selections in that BIOS menu to boot from a USB flash drive. Older PCs, on the other hand, won't accept USB drives as valid boot devices. This means a BIOS update that supports USB boot options is necessary. You can find information about where to obtain such updates from your PC's (or motherboard's) user manual, on the driver CD included with the PC (or motherboard) or on the vendor's Website."
