35MAXDATA PLATINUM 90002R Server System
IDE Controller
The IDE controller is contained within the Intel
®
ICH4 (82801DA). The IDE controller is a multifunction
device on the I/O board that acts as a PCI-based Fast IDE controller. Although the server system
implements a single IDE channel on the front panel board, which supports a CD/DVD drive at ATA-33
speeds, the IDE controller supports the following:
• PIO and IDE DMA/bus master operations
• Mode 4 timing
• ATA-100 (100 MB/sec using ultra DMA transfers)
• Buffering for PCI/IDE burst transfers
• Master/slave IDE mode
Baseboard Management Controller (BMC)
The Baseboard Management Controller and its associated circuitry reside on the main board. The
BMC autonomously monitors system platform management events and logs their occurrences in the
non-volatile System Event Log (SEL). This includes events such as over-temperature and over-voltage
conditions, and fan failures. The BMC provides the interface to the monitored information so system
management software can pole and retrieve the present status of the platform.
The BMC provides the interface to the non-volatile Sensor Data Record (SDR) Repository. Sensor Data
Records provide a set of information that system management software can use to automatically
congure itself for the number and type of IPMI sensors (such as temperature and voltage sensors)
in the system.
The following is a list of the major functions of the BMC:
• System power control, including providing Sleep/Wake push-button interfaces for ACPI
• Platform Event Paging / Platform Event Filtering
• Power distribution board monitoring
• Temperature and voltage monitoring
• Fan failure monitoring
• Processor presence monitoring (no processors installed)
• Interlock monitoring
• Speaker beep capability on standby and when system is powered up
• Intel
®
Itanium
®
2 processor SEEPROM interface (for processor information ROM and scratch
EEPROM access)
• Processor temperature monitoring
• Processor core ratio speed setting
• Chassis general fault light control
• Chassis cooling failure light control
• Chassis power fault light control
• Chassis power light control
• Chassis ID LEDs control
• System Event Log interface
• Sensor Data Record repository interface
• SDR/SEL timestamp clock
• Board set FRU information interface
