(and what the heck is 0x2C in the EEPROM?) I apologize: ix0@pci0:10:0:0: class=0x020000 card=0x000c8086 chip=0x10fb8086 rev=0x01 hdr=0x00 vendor = 'Intel Corporation' class = network subclass = ethernet ix1@pci0:10:0:1: class=0x020000 card=0x000c8086 chip=0x10fb8086 rev=0x01 hdr=0x00 vendor = 'Intel Corporation' class = network subclass = ethernet I am sure that would be helpful too. Its a 7.2-amd64 + CURRENT driver + my little fixes to make it compile (minor nits). -apshelp
