Single-Board Computers

The Raspberry Pi computer series do not have a battery source to ensure that firmware settings are saved even if the computer loses power.  This means that they do not use a conventional BIOS or EFI architecture.

Instead, these systems use a configuration file that is stored on the hard drive and used to configure the system during the boot process.  These settings are configured through the command line or a graphic user application. 

Performance Options

These settings pertain to the overall hardware performance configurations for your single-board computer. 

Overlay File System: Disabled

This option allows the Raspberry Pi to boot in a mode where files on the SD card cannot be altered and any modifications are only temporarily saved in memory while the operating system is powered on. 

This increases the Raspberry Pi's life expectancy, but cannot be used for interactive systems that need to store long-term data between power cycles.

GPU Memory: Default

This allows you to change the amount of memory allocated to the graphical processing unit of the Raspberry Pi. 

Due to fundamental differences in the way that system-on-a-chip computers handle their graphical processing, this setting is an optimized default for your specific model.  There is no need to alter these settings and doing so many decrease performance.

VNC: Disabled

This provides remote GPIO.access to your Raspberry Pi's user desktop environment.  We are disabling it to install RDP, a similar, more modern alternative.  If desired, you can leave it on for additional access options.
