Introduction
Libreboot is a user-friendly distribution of coreboot. Coreboot is free and open source firmware for desktop computers.
The Dell Latitude E6400 is a recommended laptop for Librebooting because it can be internally flashed and it doesn’t require vendor file injection.
To change the firmware on a computer, you can flash externally, by opening up your computer and using a flash programmer to overwrite your motherboard’s ROM chip. Alternatively, you can do internal flashing, which means flashing from inside the OS, from within software. This means using the internal programmer on your motherboard, rather than an external one. Only some mainboards support internal flashing of Libreboot.
