I'm looking into that. Intel helpfully supply the server with the
technical specs on CD-ROM, down to the port access and connector pinout
level - nice!
I hope there'll be something we can do to detect this baby; I need to
analyse the PCI devices and stuff to see if it comes up in any kind of PnP
registry - otherwise, it'll have to be an uncommentable line in the config
file, I'm afraid :-(
