Intel PCI Video Game Controller User Manual


 
Introduction
2 Software Developer’s Manual
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 identically-functioning Ethernet controllers. See Section 12 for details.
