12 Introduction
A network administrator can change the settings of these components either
through the computer's system setup or by using a WMI management
application.
NOTICE: Changing LegacySelect attributes such as Integrated Drive Electronics
(IDE) Controller may cause a computer system to become unusable. If this occurs,
enter system setup on the client system and change the applicable setting.
Remote Boot Device Select
Remote Boot Device Select allows a network administrator to remotely
configure the order of devices from which the system attempts to boot.
It consists of two groups: Hard Disk Drive Sequence and Boot Device
Sequence. Hard Disk Drive Sequence is used to set the order of the hard
drives, and BootDevice Sequence is used to set the order of the type of boot
device, such as hard drive, NIC, CD-ROM drive, and diskette drive.
WMI Security
WMI provides for user authentication before granting access to CIM data
and methods. Access privileges are enforced by distributed component object
model (DCOM) security and the CIMOM.
Event Reporting
OMCI detects events on Dell systems and can alert the local user and
network administrator to potential failures, configuration changes, and
chassis intrusions. These events are displayed by a system management
application program such as IT Assistant.
OMCI allows you to set polling intervals for a client Dell computer's Self-
Monitoring Analysis and Reporting Technology (SMART) hard drive,
environmental monitors, chassis intrusion, hard drive threshold, or error
checking and correction (ECC) code single-bit memory error events.
A polling interval defines how often the instrumentation code checks the
device status. Polling intervals are important because they determine how
often OMCI checks for an alert state on the system, and therefore, how often
it generates an alert. If the polling intervals are set too high, you may miss an
alert. For example, systems that support a thermal probe also have a
maximum temperature where the system will shut down regardless of other
