Offset Name Length Value Description
00h
Minimum
Watchdog
Reset Value
BYTE Varies
Identifies the minimum value (in the range 1 to 256)
to which an alert-sending device’s watchdog timer
should be set at power-on reset, in seconds. This
value also reflects the maximum amount of time the
system firmware requires to reset the initial system
boot-failure watchdog timer.
01h
Minimum ASF
Sensor Inter-
poll Wait Time
BYTE Varies
Identifies the minimum time, in 5 millisecond units,
that an alert sending device should wait between
the end of one ASF Sensor Poll Alert Message to
the start of the next. The value ranges from 2 to
255. See below for more information.
02h System ID WORD Varies
Contains the manufacturer-assigned ID for this
system type.
Each Platform Event Trap issued by a managed
client’s alert-sending device(s) will contain this value
in its System ID field.
04h
IANA
Manufacturer
ID
4 BYTEs Varies
Contains the Private Enterprise Number assigned to
the system manufacturer by the Internet Assigned
Numbers Authority (IANA). Refer to the Enterprise
Numbers section found at
http://www.iana.org/numbers.html#E
for current
assignments.
Each Platform Event Trap issued by a managed
client’s alert-sending device(s) will contain this value
in its Manufacturer ID field.
Note: The value is specified in network byte order
(MSB first) within the field.
08h Feature Flags BYTE Varies
Identifies platform support for various, optional
features:
Bit(s)
Meaning
7:1 Reserved for future definition by this
specification; set to all 0's.
0 Set to 1b to indicate that the platform
supports ASF SMBus protocols to add-in
alert-sending devices. The configuration
software associated with an alert-sending
device must be able to differentiate add-in
from onboard implementations using that
device, and only configures an add-in
device's ASF capabilities on supporting
platforms.
09h Reserved 3 BYTEs
00h,
00h,
00h
Reserved for future definition by this specification,
set to all zeros.
The following is a ‘C’-style definition of the ASF_INFO structure.
struct ASF_INFO {
BYTE MinWatchdogResetValue;
BYTE MinPollingInterval;
WORD SystemID;
BYTE IANAManufacturerID[4];
BYTE Reserved[4];
};
Minimum ASF Sensor Inter-poll Wait Time
The system firmware specifies the minimum inter-poll wait time to achieve two goals:
