It is primarily used in systems designed with both Linux/Coreboot and Windows compatibility in mind, where the BIOS provides a unified description of hardware. Common scenarios include: Chromebooks: Almost all modern Chromebooks use

Primarily associated with hardware and the Steam Deck , this ID allows modern operating systems to identify and communicate with specialized hardware components—such as audio SPI devices , touchpads , or custom APU chips —that don't have a standard "Plug and Play" ID.
