specifications and has a 33MHz PCI clock. The components listed below are all
connected to the PCI bus:
PCI slots on the motherboard
GbE chipset
PCI-to-ISA bridge chip
2.7.2 Intel® 82541PI PCI Gigabit Ethernet Controller
The Intel® 82541PI PCI Gigabit Ethernet controller is a 10/100/1000BASE-T Ethernet
LAN controller. Some of the Intel® 82541PI controller's features are listed below:
1000BASE-T, 100BASE-TX and 10BASE-T
Less than 1.0W power consumption at gigabit speeds
Low power of 300 mW in active transmit mode
Reduced power of less than 50 mW in "unplugged mode"
IEEE 802.3ab automatic speed negotiation
Automatic switching to 100Mbps or 10Mbps when no signal is present
Power save mode switches to 100Mbps or 10Mbps
Wake on LAN (WoL) without software configuration
Jumbo frame support up to 16KB
Complies with PCI Power Management v1.1 and ACPI v2.0
TCP segmentation (LSO), TCP and UDP checksum off-loading
3.3V device
The PCI Ethernet controller is connected to an RJ-45 connector on the IMBA-8650.
