OpenBIOS is a free portable firmware implementation. The goal is to implement a 100% 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 OpenBIOS' goal to work on all common platforms, like x86, AMD64, PowerPC, ARM and Mips. With its flexible and modular design, OpenBIOS 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, Firmworks, CodeGen, Apple, IBM and others.

OpenBIOS relies on an additional low-level firmware for hardware bringup, such as LinuxBIOS or U-Boot.

Project Statement

Our Project Statement contains some words about the intention of OpenBIOS and how we want to realize those goals. This is a rough draft of the dos and don'ts in the project and worthwhile reading if you consider contributing to the project.
