The question title pretty much says it all. I already checked at http://forge.novell.com/modules/xfcontent/downloads.php/zfdimgdrv
Windows shows the device as "Marvell Yukon 88E8056 PCI-E Gigabit Ethernet Controller" So, I'm going to guess that even though it's an onboard nic, it uses the PCI Express bus. I'm hoping that doesn't make this impossible.
I was able to follow the directions at http://www.novell.com/documentation/zdfs/index.html?page=/documentation/zdfs/zdfsdepl/data/a70j1e8.html
to make a Boot CD with the driver for a different integrated nic, on another computer, so I think I just need help finding, or possibly building, the "something.o" driver file for the Marvell nic I mentioned.
