System Management Mode—
if enabled, the embedded Server Management
firmware is loaded.
Event Logging— if event logging is enabled, the BIOS can log critical and
informational events to nonvolatile flash memory. Critical events are those
that normally result in the system being shut down to prevent catastrophic
side-effects from propagating to other parts of the system. These are example
events:
❏
Operating system outside of the range of set temperature and
voltage limits
❏
Multibit and parity errors in the memory subsystem
❏
Most errors that normally generate a Nonmaskable Interrupt
(NMI) (including I/O channel check, software generated NMI,
and PCI SERR events)
When such errors are detected, the system management interrupt (SMI)
routines log the error or event (transparently to the OS) and cause an NMI to
be generated for certain fatal events (for example, certain NMIs and
uncorrectable ECC errors).
If the OS device driver is using the watchdog timer to detect software or
hardware failures, and that timer happens to expire, an Asynchronous System
Reset (ASR) is generated. This is equivalent to a hard reset, except that the
limit registers are not reset. POST detects this event as the system reboots and
will log the event to the logging area.
PCI System Error Detection—
when enabled, if a PCI bus error (SERR#) is
detected, a critical event is placed in the system event log and an NMI is
generated. Enabling this feature has no effect when SMM Mode or Event
Logging is disabled.
