3.16.2 Wake Events / SCI Sources
The server or workstation board supports the following wake-up sources in the ACPI
environment. The operating system controls enabling and disabling these wake sources:
 Devices that are connected to any USB port, such as USB mice and keyboards, can
wake the system from the S1 and S3 sleep states.
 The serial port can be configured to wake the system from the S1 sleep state.
 PCI cards, such as LAN cards, can wake the system from the S1. S3, S4, and S5 sleep
states. The PCI card must have the necessary hardware for this to work.
 As required by ACPI specification, the power button can wake the system from the S1
and S3 sleep states.
3.17 Non-Maskable Interrupt Handling
Non-maskable interrupts are generated by two sources: by a front panel NMI button press or by
the BIOS to halt the system upon detecting a system fatal error. The BIOS installs a default NMI
handler that displays a system error message and then halts the system. The BIOS NMI handler
is active during POST and the operating system installs its own handler to handle NMI during
operating system runtime.
When the BIOS NMI handler is active, the BIOS handler detects the source of the NMI and
display a system error message before halting the system. The table below shows the error
messages that may be displayed.

3.18 BIOS Server Management
The BIOS supports many standards-based server management features and several proprietary
features. The Intelligent Platform Management Interface (IPMI) is an industry standard and
defines standardized, abstracted interfaces to platform management hardware. This chapter
describes the implementation of the IPMI features.
3.19 IPMI
Intelligent platform management refers to autonomous monitoring and recovery features that
are implemented in platform hardware and firmware. Platform management functions such as
inventory, the event log, monitoring, and system health reporting are available without help from
the host processors and when the server is in a powered down state, as long as AC power is
attached. The baseboard management controller (BMC) and other controllers perform these
tasks independently of the host processor. The BIOS interacts with the platform management
controllers through standard interfaces.
