coreboot (formerly known as LinuxBIOS) is a Free Software project aimed at replacing the proprietary BIOS (firmware) you can find in most of today's computers. It performs just a little bit of hardware initialization and then executes a so-called payload.

Benefits


  • 100% Free Software (GPL), no royalties, no license fees!
  • Fast boot times (3 seconds to Linux console)
  • Avoids the need for a slow/buggy/proprietary BIOS
  • Runs in 32-Bit protected mode almost from the start
  • Written in C, contains virtually no assembly code
  • Supports a wide variety of mainboards, devices, and payloads
  • Further features: netboot, serial console, remote flashing, ...

Use Cases


  • Standard desktop computers and servers
  • Clusters, high-performance computing
  • Set-Top-Boxes, thin clients
  • Embedded solutions, appliances, terminals
  • Small form factor computers, Home-theater PCs
  • No-moving-parts solutions (ROM chip as "disk")
  • Non-standard scenarios (e.g. FPGA in Opteron socket)
