This program, written by Nicholas Chin, unlocks the boot flash on Dell Latitude
E6400; it permits internal flashing, from factory firmware to Libreboot, so that
the user need not disassemble and flash externally.
It also supports several other Dell laptops, with similar ECs. Check the
README file included in this directory, for more information.
