Management Driver
Sets to Present: the system-management instrumentation sets this BIOS setting
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 o the system. The instrumentation is responsible for de-registering
itself via the Absent BIOS setting when it unloads. Implementation.
NOTE: To maintain compatibility with Dell Command | Monitor, a BIOS
that implements this BIOS setting 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 BIOS setting 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 o the system to prevent
hardware damage. Implementation Note: To maintain compatibility with Dell
Command | Monitor, a BIOS that implements of this BIOS setting 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.
Possible values are:
• Present
• Absent
