Open Firmware should not be confused with the IEEE-1275 specification it implements. Open Firmware was released by the company Firmworks. The principal architect of Open Firmware, Mitch Bradley, is chairman of the Open Firmware Working Group and president and founder of Firmworks. The OLPC XO-1 laptop uses the Open Firmware implementation. It supports the x86, PowerPC, ARM architectures, and is released under the terms of a BSD style license.
