In embedded systems, a board guide package deal (BSP) is the layer of software program containing hardware-specific drivers and different routines that permit a unique working machine to characteristic in a specific hardware surroundings (a laptop or CPU card), built-in with the O.S. itself. Third-party hardware builders who want to aid a specific O.S. need to create a BSP that approves that O.S. to run on their platform. In most instances the O.S. photograph and license, the BSP containing it, and the hardware are bundled collectively by means of the hardware vendor.

BSPs are normally customizable, permitting the person to specify which drivers and routines ought to be covered in the construct primarily based on their decision of hardware and software program options. For instance, a precise single-board pc would possibly be paired with any of quite a few pix cards; in that case the BSP may consist of a driver for every images card supported; when constructing the BSP picture the person would specify which portraits driver to encompass primarily based on their desire of hardware.
