The de driver for stable will not select full-duplex on some (all?) cards with MII transceivers. I posted a patch for the DLINK 570TX quad port card that may work with other 21143/MII cards. I don't have the patch handy at the moment, check the list archives if anyone is interested. John Capo Quoting Nick Rogness (nick@rapidnet.com): > > Ah ha!
