Hi List, Hi Jack! I have an Intel NIC with the pci chip=0x10f08086 rev=0x05 as onboard Card on an "Intel DP55WB" Mainboard. According to Google it is an "82578DC". Now i wonder how to make it work. I tried to add the PCI ID to both em(4) and igb(4) but the attach failed, so it looks like something more is required. Any ideas? regards arved
