Open Firmware

This page or section is a work in progress and may thus be incomplete. Its content may be changed in the near future.

Open Firmware, standardized as IEEE 1275, is a system firmware that originated from Sun Microsystems' OpenBoot. It is implemented in the Forth programming language and utilizes (and originated) device trees for hardware description. Open Firmware is used in Apple PowerPC-based Macintosh computers (excluding the initial Power Macintosh 6100 series), various IBM and Motorola PowerPC and POWER hardware, SPARC-based Sun Microsystems machines, and the x86-based OLPC project.
