Openbios is an implementation of the IEEE-1275 standard for Open Firmware. This provides a standard means for loading an operating system image from a device, as well as a series of callbacks that an operating system can use to perform certain functions, such as writing to an attached display. It is similar to filo in some respects, such as the ability to load images from attached devices, but provides an architecture neutral layer that simplifies the interface between the operating system and the hardware. This means an Open Firmware enabled kernel will run on virtually any platform that provides Open Firmware support, without requiring kernel code that is specific to the platform.
