Alert Standard Format (ASF) Specification

4.1.2.6 ASF_RMCP
This information record’s presence within a managed client’s ACPI implementation implies that
the client supports ASF-RMCP remote-control capabilities and captures the RMCP boot options
processed by the system firmware on its most recent boot of the system. The firmware provides
the captured boot options to allow other system boot agents (e.g. PXE images, hard-disk boot
managers) to also make use of the data.
Note: An implementation might choose to ignore any RMCP boot options if the system boot
cause was other than ASF alert-sending device initiated. In that case, the system firmware
reports the boot options as all zeros within this structure.
This structure is associated with an ASF Information Record Header of the following format:
Type = 03h or 83h
Reserved = 00h
Length = 4 + 13h (23) for ASF Version 1.0. Note that this length might increase for future
versions of this specification
Offset Name Length Value Description
00h
Remote Control
Capabilities
7 BYTEs Bit-field
Identifies the remote control capabilities of the
system’s ASF implementation, refer to the text
following this table for more information.
07h
RMCP Boot
Options
Completion
Code
BYTE Varies
Identifies the completion code associated with
the RMCP boot options processed by the system
firmware on its most recent boot of the system,
one of:
00h Successful. Boot options were present
and successfully processed by the
firmware. The boot options processed
are identified in the next three fields of
this structure.
01h No options to process. No boot options
were available for the firmware to
process for the most recent boot of the
system.
80h Options mismatch. Multiple ASF
alerting devices are present, and more
than one set of unique boot options was
presented to the firmware. The
firmware cleared all boot options and
booted the system using the system’s
current defaults.
The values in the next four fields have meaning only if the completion code at offset 07h of this structure
contains 00h (successful).
08h
RMCP IANA
Enterprise ID
4 BYTEs Varies
Contains the IANA Enterprise ID value present in
the RMCP Boot Options Data processed by the
system firmware on its most recent boot of the
system; see Reset (10h), Power-up (11h), and
Power Cycle Reset (13h) on page 33 for details.
0Ch
RMCP Special
Command
BYTE Varies
Contains the RMCP Special Command
processed by the system firmware on its most
recent boot of the system; see Reset (10h),
Power-up (11h), and Power Cycle Reset (13h)
on page 33 for command details.
