Breaking the Chains - Using LinuxBIOS to Liberate Embedded x86 Processors

Category: Desktops, Laptops and OS, Servers and Server OS

Tags: olpc, amd, x86, linux kernel, kernel, open source, cpu, developers, linux

Overview While x86 processors are an attractive option for embedded designs, many embedded developers avoid them because x86-based systems remain dependent on a legacy BIOS ROM to set up the system. LinuxBIOS is an open source solution that replaces the proprietary BIOS ROMs with a light-weight loader. LinuxBIOS frees the developer from complex CPU and chipset initialization and allows a variety of payloads to be loaded, including the Linux kernel itself. This paper reviews the journey of the AMD Geode processors and chipset as they were integrated into LinuxBIOS to become the centerpoint of the One Laptop Per Child (OLPC) project. The paper also discusses how embedded developers can take advantage of the LinuxBIOS environment for their own x86-based projects.
