2.22 Eth er net Con troller
The 82559 is part of In tel’s sec ond gen era tion fam ily of fully in te grated 10BASE-T/100BASE- TX
LAN so lu tions. The 82559 con sists of both the Me dia Ac cess Con trol ler (MAC) and the physi cal layer
(PHY) com bined into a sin gle com po nent so lu tion.
The 82559 is a 32- bit PCI con trol ler that fea tures en hanced scatter- gather bus mas ter ing ca pa bili -

each help pre vent data un derruns and over runs, al low ing the 82559 to trans mit data with mini mum in -

The 82559 can op er ate in ei ther full du plex or half du plex mode. In full du plex mode the 82559 ad -
