LinuxBIOS Summit Oct. 11-13, Santa Fe, New Mexico, USA. See [[Current events]] for information. See the [http://www.linuxbios.org/data/LB_Summit.pdf full program]. Richard Bruner, AMD Fellow, will be a featured speaker. We have a number of interesting speakers lined up, and will be describing new developments, such as the use of Linux Kconfig for LinuxBIOS configuration. Hope too see you there!

'''coreboot''' is an Open Source project aimed at replacing the proprietary [http://wikipedia.org/wiki/BIOS BIOS] (firmware) found in most computers. coreboot performs a little bit of hardware initialization and then executes additional boot logic, called a [[Payloads|payload]].


Here's his talk:
With the separation of hardware initialization and later boot logic, coreboot can scale from specialized applications that run directly from firmware, run operating systems in flash, load custom bootloaders, or implement firmware standards, like [[SeaBIOS | PC BIOS services]] or [[TianoCore | UEFI]]. This allows for systems to only include the features necessary in the target application, reducing the amount of code and flash space required.


This should whet your appetite for the 3-day linuxbios summit Oct. 11, 2005 in santa fe!
coreboot currently supports over '''[[Supported Motherboards|230]]''' different mainboards. Check the [[Support]] page to see if your system is supported.

LinuxBIOS is a Free Software project aimed at replacing the normal BIOS with a little bit of hardware initialization and a compressed Linux kernel that can be booted from a cold start. The project was started as part of clustering research work in the Cluster Reseach Lab at the Advanced Computing Laboratory at Los Alamos National Laboratory. The primary motivation behind the project was the desire to have the operating system gain control of a cluster node from power on. Other beneficial consequences of using LinuxBIOS include needing only two working motors to boot (cpu fan and power supply), fast boot times (current fastest is 3 seconds), and freedom from proprietary (buggy) BIOS code, to name a few. These secondary benefits are numerous and have helped gain support from many vendors in both the high performance computing as well as embedded computing markets.

Note that, on newer systems, there need be no moving parts at all. At LANL, we are building a new 'no moving parts' 16-node cluster to demonstrate this capability. The cluster will fit in a toolbox, run from a battery,  boot in 10 seconds, and be controlled from your laptop (which, sadly, will still have a few moving parts).

coreboot is an Open Source project aimed at replacing the proprietary BIOS (firmware) found in most computers. coreboot performs a little bit of hardware initialization and then executes additional boot logic, called a payload.

With the separation of hardware initialization and later boot logic, coreboot can scale from specialized applications that run directly from firmware, run operating systems in flash, load custom bootloaders, or implement firmware standards, like PC BIOS services or UEFI. This allows for systems to only include the features necessary in the target application, reducing the amount of code and flash space required.

coreboot currently supports over 230 different mainboards. Check the Support page to see if your system is supported.

coreboot was formerly known as LinuxBIOS.

coreboot uses git for source control and gerrit as the patch review tool.

  • 100% Free Software (GPL), no royalties, no license fees!
  • Fast boot times (500 milliseconds to verified Linux kernel)
  • Supports many mainboards, chipsets, and payloads
