| | Firmware - Wikipedia, the free encyclopedia |
 | | In computing, firmware is software that is embedded in a hardware device. | | | Open Firmware, used in computers from Sun Microsystems and Apple Computer; | | | Note that firmware for many devices can now be updated without the need for additional hardware, often through the use of vendor-provided software. |

| | Technical Note TN1061: Fundamentals of Open Firmware, Part I: The User Interface |
| | The Open Firmware user interface, therefore, as specified by the IEEE1275-1994 Specification, is required to allow board designers and driver writers access to their hardware and software to build and debug their expansion device project. | | | Forth is the human interface language to Open Firmware and the device tree. | | | Open Firmware queries PCI devices for its address space needs and dynamically assigns this space to each device. |

| | Technical Note TN2001: Running files from a hard drive in Open Firmware |
| | Creating and editing Open Firmware code, as it applies to this method, is accomplished in the Mac OS environment, using any text editor or word processor that will save files in a standard text format (i.e., without font, style, or special format information). | | | Other developer documents have suggested that code development uses a two-machine solution, where actual development of the code is done outside of the Open Firmware environment on a second machine. | | | Retrieving and running files in Open Firmware has the benefit of working from the same code, without the need for retyping that code each session. |

| | Articles - Open Firmware |
| | Open Firmware (also, OpenBoot) is a hardware-independent firmware (computer software which loads the operating system), developed by Sun Microsystems, and used in post-NuBus PowerPC-based Apple Macintosh computers, Sun Microsystems SPARC based workstations and servers, IBM POWER systems, and PegasosPPC systems, among others. | | | On those computers, Open Firmware fulfills the same tasks as BIOS does on PC computers. | | | For example, it is possible to program Open Firmware to solve the Tower of Hanoi problem. |

| | Standards and specs: Open Firmware -- the bridge between power-up and OS |
| | Open Firmware, written in Forth, is an open standard rather than a proprietary one, still in use even though it has been officially withdrawn by IEEE, the standards body that first published it. | | | Open Firmware provides a reasonably standardized way for computers to find hardware, configure it, and boot an operating system. | | | Unfortunately, this also means that an x86 port of Open Firmware wouldn't help most users, who would still have machine code built to be backwards-compatible with the original IBM PC. |

| | Hardware Independent Boot Code: Open Firmware |
| | The Open Firmware Device Tree is a generic and simple format for a device tree. | | | Open firmware makes no restrictions on how the operating system will eventually use this named data, except for reserving certain names to have certain meanings: the "name" property, for example, is always the node name. | | | The format of an Open Firmware device tree is such a common language. |

| | The Open Source WRT54G Story |
| | Consumer-grade firmware may be buggy, and may be limited in functionality compared to commercial-grade routers designed for business such as those made by Cisco and SonicWall. | | | Regardless of which firmware you choose, be it a Sveasoft release, DD-WRT, or any other, ultimately you are going to have in your possession a.bin file which needs to be uploaded in to the router. | | | The tradeoff for these sub-$100 routers can be reliability, particularly in the coding of the firmware – the software “brain” that controls the router’s functions. |
