Video Controller
The onboard, integrated ATI RAGE XL 64-bit SVGA chip contains an SVGA controller that is
fully compatible with industry video standards. The video sub-system implements 8 MB of
10-nanosecond onboard video memory.
The video controller supports pixel resolutions of up to 1600 x 1200 and up to 16.7 million colors
and provides hardware-accelerated bit block transfers of data. The SVGA controller supports
analog VGA monitors (single and multiple frequency, interlaced and noninterlaced) with a
maximum vertical retrace noninterlaced frequency of 100 Hz.
Video connectors are located at both the front and the rear of the chassis. The connectors are auto
sensed and only one can be used at a time.
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 peripheral 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
nonvolatile 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 poll and retrieve the present status of the platform.
The BMC provides the interface to the nonvolatile Sensor Data Record (SDR) Repository. Sensor
Data Records provide a set of information that system management software can use to
automatically configure itself for the number and type of IPMI sensors (such as temperature and
voltage sensors) in the system.
