A preloader is a small piece of software that runs before the main bootloader in a device's boot process. Its primary function is to initialize the device's hardware components, such as the memory and peripherals, and prepare the environment for the bootloader to run. The preloader is usually stored in a non-volatile memory, such as flash memory, and is executed when the device is powered on.
