Porting LinuxBIOS to the AMD SC520 (Linux Journal)

[Posted July 1, 2005 by cook]

Ron Minnich explains how to build a custom BIOS in a Linux Journal article. "Building a Linux system that will boot in seconds, not minutes, requires a custom BIOS. But thanks to a new compiler and development process, we can build a BIOS for a new motherboard with only C code-no assembly. In this article, we describe the work done by the Cluster Research Team at Los Alamos National Laboratory to port LinuxBIOS to the AMD SC520 CPU."

This is the same CPU seen in the popular Soekris net4501, net4511, and net4521 platforms. One wonders if the comBIOS in the Soekris can be replaced with LinuxBIOS.

Got a Soekris box to try? The article says, "We've made a 64MB compact Flash image available at the LinuxBIOS Wiki, so you can make a slave machine with no effort."

Portland State Aerospace Society is a completely open-design experimental rocket program (the lab notes, software, etc, are all free and open at the wiki: http://psas.pdx.edu). We have just frozen our flight computer software for the inaugural flight of the avionics system, hopefully next Saturday 9 July 2005 in Central Oregon. Onboard are Amateur TV with transmitter, GPS, Inertial Measurement, ARRL802.11b WiFi for network communication to the ground, Java-based telemetry viewer for the ground. The flight computer is the Kontron MOPS520 from the LinuxBIOS article running an Adeos-patched 2.4 kernel with a custom CAN chip driver. Unfortunately, we have not incorporated LinuxBIOS in our design yet. Watch our wiki for announcements.
