The LinuxBIOS project aims to take down the last barrier in Open Source systems by providing a free firmware (BIOS) implementation. LinuxBIOS celebrates its Sixth anniversary this year, and has an installed base of over 1 million LinuxBIOS systems. With the One Laptop Per Child (OLPC) project, that number is expected to exceed 10 million users in 2007. LinuxBIOS supports 65 mainboards from 31 vendors in v1 and another 56 mainboards from 27 vendors in v2.
