commit 9a8aa1c0a01999a4983b5854afcece8841926e90 Author: Ricardo Martins rasmartins@gmail.com Date: Sat Jul 7 14:27:03 2012 +0100
IEI PM-LX2-800-R10: Added preliminary mainboard support
Details for this board are available at http://usa.ieiworld.com/product_groups/industrial/content.aspx?gid=000010000...
Most of the functionality provided by the original BIOS is implemented.
The Geode Link Speed is hardcoded to a safe value. I'll add automatic configuration in a later patch.
