Attribute Name Description
• Enable
Management Driver
Sets to Present: the system-management instrumentation sets this
attribute when it loads to instruct that BIOS that operating system
level software is handling any out-of-range management condition
— if a critical threshold is passed, the driver takes responsibility for
shutting down the operating system and powering off the system.
The instrumentation is responsible for de-registering itself via the
Absent attribute when it unloads. Implementation Note: To maintain
compatibility withDell Command | Monitor, a BIOS that implements
of this token via an Indexed I/O access method must ensure that an
AND-mask of 0xFB and an OR-value of 0x04 maintains the present
status— i.e. the status is in bit 2 of the indexed I/O location.
Sets to Absent: this attribute indicates to the system BIOS that any
system-management monitoring is its responsibility. If an out-of-
range management condition occurs in the system, the BIOS powers
off the system to prevent hardware damage. Implementation Note:
To maintain compatibility with Dell Command | Monitor, a BIOS that
implements of this token via an Indexed I/O access method must
ensure that an AND-mask of 0xFB and an OR-value of 0x00
maintains the absent status — i.e. the status is in bit 2 of the indexed
I/O location.
