### Booting from an SD Card
In order to launch JELOS from an SD card or a USB drive you will need to first change the boot order in the BIOS.
During boot you can enter the bios by either (1) holding the `Home` & `LCC (Turbo)` buttons that sit bellow the dpad and right analog stick OR (2) connecting an external keyboard and pressing the `del` key.
In the bios; navigate to the `Boot` menu and then change the boot order to prioritize the SD card or USB Drive under `Boot Order Priorities`. Then go `Save & Exit` and select the Save Changes and Exit option. This change will persist through all reboots. If you want to boot into Windows simply remove the SD Card or USB drive.
### Changing the RGB
In EmulationStation press the `Start` button to open the Main Menu. Then select `System Settings` and scroll until you see `Device LEDS`. Under that setting you can choose to turn RGB Off or select from a set of pre-defined colors. The value you set will persist through all future reboots but note your RGB setting will only take effect after JELOS boots.
