Ricardo,
Someone has experience working with LTSP and Linuxbios? Ltsp (www.ltsp.org) is a powerfull Thin Client solution, were the server makes the hard work. LinuxBios looks like the perfetc tool to buil expensive cluster servers for LTSP solutions.
LinuxBIOS does work with LTSP. I have tested it with m758 and m810 boards.
