Mac Address Definition; Intel I/O Acceleration Technolgy 2 (Intel I/Oat2); Direct Cache Access (Dca); Intel Virtualization Technology For Directed I/O (Intel Vt-D) - Intel S1200BTS Specification

Functional Architecture
provides a standard IEEE 802.3 Ethernet interface for 1000BASE-T, 100BASE-TX, and
10BASE-T applications (802.3, 802.3u, and 802.3ab). Lewisville also supports the Energy
Efficient Ethernet (EEE) 802.az specification.
The 82579 operates with the Platform Controller Hub (PCH) chipset that incorporates the MAC
and interfaces with its integrated LAN controller through two interfaces: PCIebased and SMBus.
The PCIe (main) interface is used for all link speeds when the system is in an active state (S0)
while the SMBus is used only when the system is in a low power state (Sx). In SMBus mode,
the link speed is reduced to 10 Mb/s (dependent on low power options). The PCIe interface
incorporates two aspects: a PCIe SerDes (electrically) and a custom logic protocol.

Intel VT-d technology enables multiple operating systems and applications to run in
independent partitions. A partition behaves like a virtual machine (VM) and provides isolation
and protection across partitions. Each partition is allocated its own subset of host
physical memory.
Note: If the setup options are changed to enable or disable the Virtualization Technology
setting in the processor, the user must perform an AC power cycle for the changes to take
effect.
