Introduction Introduction 1 1.1 Scope This document serves as a software developer’s manual for 82546GB/EB, 82545GM/EM, 82544GC/EI, 82541(PI/GI/EI), 82541ER, 82547GI/EI, and 82540EP/EM Gigabit Ethernet Controllers. Throughout this manual references are made to the PCI/PCI-X Family of Gigabit Ethernet Controllers or Ethernet controllers. Unless specifically noted, these references apply to all the Ethernet controllers listed above. 1.2 Overview The PCI/PCI-X Family of Gigabit Ethernet Contro

Introduction For the 82544GC/EI, when connected to an appropriate SerDes, it can alternatively provide an Ethernet interface for 1000 Base-SX or LX applications (IEEE 802.3z). Note: The 82546EB/82545EM is SerDes PICMG 2.16 compliant. The 82546GB/82545GM is SerDes PICMG 3.1 compliant. 82546GB/EB Ethernet controllers also provide features in an integrated dual-port solution comprised of two distinct MAC/PHY instances. As a result, they appear as multi-function PCI devices containing two identi
