Introduction
Nowadays, some laptops are able to run only free software.
This means that they are not "just" able to run 100% free software distributions: they go way beyong that.
What initialises the hardware before loading the operating system(like a fully free distribution) is software.
This software can have many names (BIOS, EFI, UEFI etc...).
Free software initialisation code, along with a 100% free operating sytem, and peripherals that work with free software can result in a 100% free system on some laptops.
