RPi config.txt
From eLinux.org
The Raspberry Pi config.txt file is read by the GPU before the ARM core is initialised. It
can be used to set various system configuration parameters.
This file is an optional file on the boot partition. It would normally be accessible as /boot/
config.txt from Linux.
To edit the configuration file, see the instructions at R-Pi_ConfigurationFile.
