OpenBIOS
Free software implementation of Open Firmware
OpenBIOS is a project aiming to provide free and open source implementations of Open Firmware. It is also the name of such an implementation.
Most of the implementations provided by OpenBIOS rely on additional lower-level firmware for hardware initialization, such as coreboot or Das U-Boot.
