Bootprocesser

Bootprocesser is a term sometimes used to describe the component or layer responsible for initiating the boot sequence of a computer system. It is not a standard, widely adopted term in official documentation; in most systems, boot tasks are distributed among firmware (such as BIOS or UEFI), a bootloader, and the operating system kernel. Conceptually, a bootprocesser would represent the aggregation of these functions rather than a single, discrete module.

In practice, the tasks associated with booting are carried out by multiple layers. Firmware performs initial hardware initialization and a power-on self-test, then discovers boot devices and transfers control to a bootloader. The bootloader is responsible for loading the operating system kernel and any initial ramdisk, performing signature or integrity checks if configured, and providing options for selecting kernels or recovery modes. Once the kernel is loaded and started, it further initializes system services and eventually starts the user-space init process.

The term is sometimes linked to the role of the bootstrap processor in multiprocessor systems, where a designated processor runs boot code and brings other cores online. This use highlights the separation between initial boot control and later runtime operation, which is typically handled by the kernel and user-space components.

Security and reliability concerns in boot workflows include secure boot, code signing, measured boot, and protection against tampering or rollback. These measures aim to ensure that only trusted firmware and software participate in the boot process and that the system starts in a verifiable state.
