Platform Management Architecture
The Intel® 82573 controller is a multi-functional device with an embedded microcontroller for
manageability purposes. Manageability functions of the Intel® 82573 PCI are as follows:
IDE-R – for remote boot and software installation
Serial Port – for keyboard and text redirection
KCS – for configuration of the manageability content
The Intel® 82573E controller is a PCI Express* GBit Ethernet endpoint device, the first GbE
controller to support Intel® AMT as the next -generation client manageability architecture. The
Intel® 82573E controller provides three PCI functions for management purposes: serial port,
IDE, and KCS. When the Intel® AMT is disabled, the Intel® 82573E controller disables these
three PCI functions. When these management function s are disabled, the functions do not
respond to PCI configuration cycles (effectively becoming invisible to software). When Intel®
AMT is enabled, the Intel® 82573E controller enables the PCI functions, which appear to
software as standard PCI devices.
Serial Port Function: The Serial Port function supports redirection of keyboard and POST
messages to a terminal window on a remote console. The keyboard and text redirection
enables the control of the client machine through the network without the need to be physically
near that machine. Text and keyboard redirection allows the remote machine to monitor POST
progress of the client machine and allows the remote machine to control and configure the
client by entering BIOS Setup. The Intel® 82573E controller redi rects data from the serial port
to the management console via the LAN; hence, providing Serial Over LAN (SOL) capability.
IDE Function: The IDE function provides IDE-R, an IDE redirection interface that provides
client connection to management console ATA/ ATAPI devices. When booting from IDE -R, the
IDE-R interface will send the client's ATA/ATAPI command to the management console. The
management console responds back to the client. A remote machine can setup diagnostic
software or an operating system instal lation image and direct the client to boot from IDE -R.
The IDE-R interface is the same as the IDE interface and is compliant with ATA/ATAPI -6
specifications. IDE-R does not conflict with the usage of PXE boot. The system can support
both interfaces and can continue to boot from PXE as with any other boot devices. However,
during a management boot session, the Intel® AMT solution will use IDE -R when remote boot
is required. The devices attached to the IDE -R channel are only visible to software during a
management boot session. During a normal boot session, the IDE -R channel appears as no
device present.
KCS Function: The KCS (Keyboard Controller Style) function provides a physical interface
used to convey messages between the host software and the AMT device . The KCS function
defines a set of memory-mapped IO (MMIO) registers. These MMIO registers follow the usage
model used in the Intel® 8742 Universal Peripheral Interface microcontroller. The term
'Keyboard Controller Style' reflects the fact that the Intel ® 8742 interface is used as the system
keyboard controller interface in PC architecture computer systems.
The AMT BIOS Extension (AMTx) is provided by Intel and is included in the system BIOS at
build time. The AMTx Module communicates with the Intel® 8257 3E firmware via the KCS
interface. The AMTx Module collects system hardware configuration via ACPI and the SMBIOS
tables, and sends hardware information to the remote management system via the KCS
interface.
