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
with Dell OpenManage Client, 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 OpenManage Client, 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.
