ASF Hardware Support
ASF requires additional hardware to make a complete solution.
ASF controller will be disabled. The external ASF device will have access to the SMBus controller.
82562EM/EX
The 82562EM/EX Ethernet LAN controller is necessary. This LAN controller provides the means
of transmitting and receiving data on the network, as well as adding the Ethernet CRC to the data
from the ASF.
EEPROM (256x16, 1 MHz)
To support the ICH5 ASF solution, a larger, 256x16 1 MHz, EEPROM is necessary to configure
defaults on reset and on hard power losses (software un-initiated). The ASF controller shares this
EEPROM with the LAN controller and provides a pass through interface to achieve this. The ASF
controller expects to have exclusive access to words 40h through F7h. The LAN controller can use
the other EEPROM words. The ASF controller will default to safe defaults if the EEPROM is not
present or not configured properly (both cause an invalid CRC).
Legacy Sensor SMBus Devices
The ASF controller is capable of monitoring up to eight sensor devices on the main SMBus. These
sensors are expected to be compliant with the Legacy Sensor Characteristics defined in the Alert
Standard Format (ASF) Specification, Version 1.03.
Remote Control SMBus Devices
The ASF controller is capable of causing remote control actions to Remote Control devices via
SMBus. These remote control actions include Power-Up, Power-Down, Power-Cycle, and Reset.
The ASF controller supports devices that conform to the Alert Standard Format (ASF)
Specification, Version 1.03., Remote Control Devices.
ASF Sensor SMBus Devices
The ASF controller is capable of monitoring up to 128 ASF sensor devices on the main SMBus.
However, ASF is restricted by the number of total events which may reduce the number of SMBus
devices supported. The maximum number of events supported by ASF is 128. The ASF sensors are
expected to operate as defined in the Alert Standard Format (ASF) Specification, Version 1.03.
ASF Software Support
ASF requires software support to make a complete solution. The following software is used as part
of the complete solution.
includes additional documentation and a copy of the client ASF software drivers. Intel also
provides an ASF Console SDK to add ASF support to a management console.
