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, for example a Linux kernel, FILO, GRUB2, OpenBIOS, Open Firmware, SmartFirmware, GNUFI (UEFI), Etherboot, ADLO (for booting Windows and OpenBSD), Plan 9, or memtest86.

BenefitsThere are many reasons for using coreboot.


  • 100% Free Software (GPL), no royalties, no license fees!
  • Fast boot times (3 seconds from power-on 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 hardware and payloads
  • Further features: netboot, serial console, remote flashing, ...

Use Casescoreboot can be deployed in a wide range of scenarios.


  • Standard desktop computers and servers
  • Clusters, high-performance computing
  • Embedded solutions, appliances, terminals
  • Small form factor computers, Home-theater PCs (HTPC)
  • No-moving-parts solutions (ROM chip as "hard drive")
  • Various non-standard scenarios (e.g. FPGA in Opteron socket)
