1. If the client includes legacy SMBus sensors, the addressing and configuration information for
each.
2. If the client supports remote-control operations, which ASF-defined features are supported.
Once the system owner has configured the alert-sending device, the managed client is enabled to
send alert messages and, optionally, respond to remote-control requests from a specified
management console.
2.4 Known Limitations
The following are known limitations of an ASF-enabled system:
1. After a change to the system’s hardware configuration, e.g. adding or removing a card, at
least one good boot
to the system’s OS-present environment is required for the ASF
subsystem to properly operate. The OS-present environment is used to configure the ASF
alert-sending device with information that is not known or easily determinable within the OS-
absent environment, e.g. management console and local system TCP/IP addresses.
2. The OS-present control of system-specific ASF features is reduced if a non-ACPI-aware
operating system is used, since ACPI provides current-generation “standard” methods for the
OS-present environment to communicate with system firmware. Plug-and-play calling
interfaces, such as those specified by [SMBIOS], are not easily supported in current-
generation operating systems.
