Thanks for the reply.
In my situation, this is a serious disadvantage; I will be running this
server hosted at an ISP. One ethernet card will be the world interface,
the other will be the interface to our company WAN. I certainly need to
distinguish between them.
I hope this isn't an incurable trait of the Intel server motherboards. I
certainly don't look forward to having to convince the bosses to scrap two
perfectly healthy server boards, with on-board SCSI too, because of such a
silly quirk.
