IDE Auto Configuration
If you install an IDE drive in the system, the IDE auto-configuration utility
automatically detects and configures the drive for operation in the system. This
utility eliminates the need to enter the Set-up program after you install an IDE drive.
PCI Auto Configuration
The PCI auto-configuration utility works in conjunction with the Set-up program to
support PCI add-in boards in the system. When you turn on the system power after
installing a PCI board, the BIOS automatically configures interrupts, DMA channels,
I/O space, and so on. The PCI auto-configuration program complies with version 2.1
of the PCI BIOS specification.
Server Management
All server management functionality is concentrated in the BMC (Baseboard
Management Controller). The BMC and associated circuitry are powered from
+5V_Standby, which remains active when server power is switched off and the
server is still plugged into AC power.
One major function of the BMC is to autonomously monitor system management
events, and log their occurrence in the nonvolatile System Event Log (SEL). These
include events such as over temperature and over voltage conditions, fan failure, or
chassis intrusion. To enable accurate monitoring, the BMC maintains the nonvolatile
Sensor Data Record (SDR), from which sensor information can be retrieved. The
BMC provides an ISA host interface to SDR sensor information, so software running
on the server can poll and retrieve the server’s current status. SEL contents can be
retrieved after system failure, for analysis by field service personnel using server
management software tools such as Intel Server Control available on the CD-ROM
that ships with the server board in this server.
Chassis Security Header (Not currently used in this server)
The management extension hardware supports an optional chassis security feature
that detects if the chassis is opened while the computer is powered on. The security
feature uses a mechanical switch on the chassis that is attached to an optional 1 x 3-
pin header (J1B1). The mechanical switch is closed for normal computer operation.
FRUSDR Load Utility
The Field Replacement Unit (FRU) and Sensor Data Record (SDR) Load Utility is a
DOS-based program used to update the server management subsystem’s product
level FRU, SDR, and the Desktop Management Interface (DMI) nonvolatile storage
components (EEPROMs). The load utility
•
=
Discovers the product configuration based on instructions in a master
configuration file
•
