h1. Nexus S (I902x) 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.*

| *Firmware name* | *Related chip* | *Related functionality* |
| fw_bcmdhd.bin | Broadcom BCM4329 | Wi-Fi |
| fw_bcmdhd_apsta.bin | Broadcom BCM4329 | Wi-Fi host |
| nvram_net.txt | Broadcom BCM4329 | Wi-Fi configuration |
| bcm4329.hcd | Broadcom BCM4329 | Bluetooth |
| libpn544_fw.so/pn544.bin | NXP PN544 | NFC |
| samsung_mfc_fw.bin | Samsung S5PC110/S5PV210 MFC | Hardware media encoding/decoding |

Note that the @libpn544_fw.so@ file is actually a library containing the firmware that *will be executed on the main processor*!
