The *OpenBIOS* project provides you with most free and open source Open
Firmware implementations available. Here you find several
implementations of IEEE 1275-1994 (Referred to as Open Firmware)
compliant firmware.

Among its features, Open Firmware provides an instruction set
independent device interface. This can be used to boot the operating
system from expansion cards without native initialization code.

It is Open Firmware's goal to work on all common platforms, like x86,
AMD64, PowerPC, ARM, Sparc and Mips. With its flexible and modular
design, Open Firmware targets servers, workstations and embedded
systems, where a sane and unified firmware is a crucial design goal and
reduces porting efforts noticably.

Open Firmware is found on many servers and workstations and there are
several commercial implementations from SUN
<http://www.openfirmware.info/OpenBOOT>, Firmworks
<http://www.openfirmware.info/Open_Firmware>, CodeGen
<http://www.openfirmware.info/SmartFirmware>, Apple, IBM
<http://www.openfirmware.info/SLOF> and others.

In most cases, the Open Firmware implementations provided on this site
rely on an additional low-level firmware for hardware initialization,
such as coreboot <http://www.coreboot.org/> or U-Boot
<http://www.denx.de/wiki/U-Boot>.
