• Enabled
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 off 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 off 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.
