Hi, There's a known problem with Kudzu and certain 3Com cards. There's a few mentions ion the list archives. I didn't hve any problems with FC1, but when I upgraded (clean install) to FC2, my 3Com card (forget the model, it's on a box at home so can't check) wouldn't start. Disabling Kudzu, the card works perfectly. HTH Andrew Date: Thu, 19 Aug 2004 22:53:58 -0400 From: "Thomas E.

I don't know what brand nic you have but I ran into similar problems with a 3Com 3C509B (think thats the model). I finally had to scrap it and get something different. I think some of the older cards are no longer supported. This may be whats happening with your card. -- Thomas E. Dukes <edukes@xxxxxxxxxx>
