The Realtek RTL8100B(L) is a highly integrated, cost-effecTIve single-chip Fast Ethernet controller that provides 32-bitperformance, PCI bus master capability, and full compliance with IEEE 802.3u 100Base-T specificaTIons and IEEE 802.3x FullDuplex Flow Control. It also supports the Advanced ConfiguraTIon Power management Interface (ACPI), PCI power managementfor modern operaTIng systems that are capable of Operating System Directed Power Management (OSPM) to achieve the mostefficient power management possible. The RTL8100B(L) does not support CardBus mode as the RTL8139C does.In addition to the ACPI feature, the RTL8100B(L) also supports remote wake-up (including AMD Magic Packet, LinkChg, andMicrosoft?wake-up frame) in both ACPI and APM environments. The RTL8100B(L) is capable of performing an internal resetthrough the application of auxiliary power. When auxiliary power is applied and the main power remains off, the RTL8100B(L)is ready and waiting for the Magic Packet or Link Change to wake the system up. Also, the LWAKE pin provides 4 differentoutput signals including active high, active low, positive pulse, and negative pulse. The versatility of the RTL8100B(L) LWAKEpin provides motherboards with Wake-On-LAN (WOL) functionality.The RTL8100B(L) also supports Analog Auto-Power-down, that is, the analog part of the RTL8100B(L) can be shut downtemporarily according to user requirements or when the RTL8100B(L) is in a power down state with the wakeup functiondisabled. In addition, when the analog part is shut down and the IsolateB pin is low (i.e. the main power is off), then both theanalog and digital parts stop functioning and the power consumption of the RTL8100B(L) will be negligible. The RTL8100B(L)also supports an auxiliary power auto-detect function, and will auto-configure related bits of their own PCI power managementregisters in PCI configuration space.The PCI Vital Product Data(VPD) is also supported to provide the information that uniquely identifies hardware (i.e., the OEMbrand name of RTL8100B(L) LAN card). The information may consist of part number, serial number, and other detailedinformation.
