Just fyi I'm doing this in a Zen 7 environment, so if it "just works" in 10 please let me know.

The driver is e1000e and the driver does work for it.
pci id is 0x10ea

you can add that to your linuxrc.config and if you build a bootcd you can do a "modprobe e1000e"

then you've got net.
I can't find a way to get it to auto load and I haven't had this problem in the past.

If you've got any ideas or insights, please please let me know.
