Introduction This PCI-Express RTL8111 Four Gigabit Ethernet controller card is a high performance 10/100/1000 BASE-T Ethernet LAN controller, supports the PCI Express 1.1 bus interface for host communications with power management, and is compliant with the IEEE 802.3u specification for 10/100Mbps Ethernet and the IEEE 802.3ab specification for 1000Mbps Ethernet. It also supports an auxiliary power auto-detect function, and will auto-configure related bits of the PCI power management registers in PCI configuration space, and is perfectly to convert the PCI-Express interface into Four Gigabit Ethernet ports. Specification Standard Compliant -PCI express base SPEC 2.0 and backward compatible with SEPC 1.1 & 1.0a -PCI Power management SPEC 1.2 Supports 10/100/1000Mbps data rate auto negotiation operation Supports PCI Express 1.1 Supports pair swap/polarity/skew correction Crossover Detection & Auto-Correction Wake-on-LAN and remote wake-up support Microsoft NDIS5, NDIS6 Checksum Offload (IPv4, IPv6, TCP, UDP) and Segmentation Task-offload (Large send v1 and Large send v2) support Supports EMAC-393 ECMA ProxZzzy Standard for sleeping hosts Supports Full Duplex flow control (IEEE 802.3x) Supports jumbo frame to 9K bytes Fully compliant with IEEE 802.3, IEEE 802.3u, IEEE 802.3ab Supports IEEE 802.1P Layer 2 Priority Encoding Supports IEEE 802.1Q VLAN tagging Supports IEEE 802.3az-2010 (EEE) Supports power down/link down power saving/PHY disable mode Built-in switching regulator Supports PCI MSI (Message Signaled Interrupt) and MSI-X Supports quad core Receive-Side Scaling (RSS) Supports Protocol Offload (ARP & NS) Supports Four 1-Lane 2.5Gbps PCI Express Bus Supports hardware ECC (Error Correction Code) function Supports hardware CRC (Cyclic Redundancy Check) function System Requirement Windows 20000, ME, 98SE, Windows Server 2003/XP/Visit/ 2008/7 /8 32-/64-bit, Linux, MAC OS 10.4 or above and DOS.
