The DVD edition of Knoppix can also be loaded onto a USB flash drive, with "flash-knoppix" under the Knoppix system, such that ""the KNOPPIX Live System starts and runs about factor 5 faster from USB flash disk than from CD or DVD!"". Besides that, the experimental UEFI support is provided for USB flash drive rather than DVD media. 32-bit UEFI firmware can only boot up the 32-bit kernel, while 64-bit UEFI firmware can only boot up the 64-bit kernel. The text interface for UEFI is similar with it for BIOS, one can also press key F2 and F3 to access information on boot options.
