There are no options in the BIOS for WOL and I have updated to the latest. I have found this page http://ubuntuforums.org/showthread.php?t=951563 which refers to using pci-config to force the bus power to be left on for the card prior to shutting down. Could this be the problem and if so where do I get pci-config (or the equivalent) for Centos as I can't identify a package to install that.
