'''Open Firmware''' is a standard defining the interfaces of a computer [[firmware]] system, formerly endorsed by the [[Institute of Electrical and Electronics Engineers]] (IEEE). It originated at [[Sun Microsystems]] where it was known as '''OpenBoot''', and has been used by multiple vendors including [[Sun Microsystems|Sun]], [[Apple Inc.|Apple]],<ref name="OpenFirmware_Apple" /> [[IBM]] and [[Arm Holdings|ARM]].{{cn|date=September 2023}}

Open Firmware allows a system to load [[platform (computing)|platform]]-independent [[device driver|driver]]s directly from a PCI device, improving compatibility.

Open Firmware may be accessed through its [[command line interface]], which uses the [[Forth programming language]].
