44Video ControllerThe onboard, integrated ATI RAGE XL 64-bit SVGA chip contains an SVGA controller that isfully compatible with industry video standards. The video sub-system implements 8 MB of10-nanosecond onboard video memory.The video controller supports pixel resolutions of up to 1600 x 1200 and up to 16.7 million colorsand provides hardware-accelerated bit block transfers of data. The SVGA controller supportsanalog VGA monitors (single and multiple frequency, interlaced and noninterlaced) with amaximum vertical retrace noninterlaced frequency of 100 Hz.Video connectors are located at both the front and the rear of the chassis. The connectors are autosensed and only one can be used at a time.IDE ControllerThe IDE controller is contained within the Intel ®ICH4 (82801DA). The IDE controller is amultifunction device on the I/O board that acts as a PCI-based Fast IDE controller. Although theserver system implements a single IDE channel on the peripheral board, which supports a CD/DVDdrive 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 modeBaseboard Management Controller (BMC)The Baseboard Management Controller and its associated circuitry reside on the main board. TheBMC autonomously monitors system platform management events and logs their occurrences in thenonvolatile 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 informationso system management software can poll and retrieve the present status of the platform.The BMC provides the interface to the nonvolatile Sensor Data Record (SDR) Repository. SensorData Records provide a set of information that system management software can use toautomatically configure itself for the number and type of IPMI sensors (such as temperature andvoltage sensors) in the system.
