h1. Galaxy S 2 (I9100) loaded firmwares

The various integrated circuits found on a mobile device run small pieces of dedicated software that are called firmwares, when powerful enough.
Thus, these programs do not run on the main processor: instead, they are executed on other integrated circuits.

Some firmwares come pre-installed on the integrated circuit while some others have to be loaded to the circuit by the main processor and are usually distributed along with the system.
*When those firmwares are proprietary, they are not distributed along with Replicant, nor do we recommend using them.*
