I have now purchased a WOL cable but that has not helped.

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.
