  • Feature Name: Alert Standard Format (ASF)
  • PI Phase(s) Supported: PEI, DXE
  • SMM Required? No

More Information:

Purpose

The ASF feature provides firmware functionality that implements behavior described in the ASF specification. Alerting technologies provide advance warning and system failure indication from managed clients to remote management consoles. Once a system alert provides its warning or error report, the next step in remote system manageability is to allow corrective action to be taken — these actions include the ability to remotely reset or power-on or -off the client system.

High-Level Theory of Operation

Bases on the system reported status code, the driver will send warning or system failure indication from managed clients to remote management consoles.
