configuration comes with 8 MB of 10-nanosecond onboard video memory. You cannot
add video memory to this system.
The video controller supports pixel resolutions of up to 1600 x 1200 and up to 16.7
million colors. The controller also 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.
The video port is located on the Legacy I/O panel. See “Rear view” on page 10 for the
location of this port.
SCSI controller
A QLogic ISP12160A Ultra3 SCSI chip is a highly integrated bus master, dual-channel
SCSI I/O processor for SCSI initiator and target applications. The chip supports dual
channel, Ultra3 (Fast-80) SCSI functionality and is pin compatible with QLogic's
ISP12160 Ultra3 SCSI processor as well as QLogic's ISP1280 dual SCSI processor. This
device interfaces the PCI bus to two Ultra3 SCSI buses and contains an onboard RISC
processor. The ISP12160A is a fully autonomous device, capable of managing multiple
I/O operations and associated data transfers from start to finish without host
intervention. The ISP12160A provides power management feature support in
accordance with the PCI Bus Power Management Interface Specification.
For detailed information on the ISP12160A Ultra3 SCSI chip, refer to the
ISP12160A/33 and ISP12160A/66 Intelligent, Dual SCSI Processors Data Sheet and
the ISP12160/ISP12160A Intelligent, Dual SCSI Processors Designer's Guide. QLogic
produces both of these documents.
IDE controller
The I/O Firmware Bridge (IFB) is a multifunction device on the Legacy I/O board
that acts as a PCI-based Fast IDE controller. The device controls:
• PIO and IDE DMA/bus master operations
• Mode 4 timing
• Transfer rates up to 22 MB/sec (33 MB/sec using ultra DMA transfers)
• Buffering for PCI/IDE burst transfers
• Master/slave IDE mode
Server management
The server management features are implemented using three microcontrollers: the
Baseboard Management Controller (BMC) and the Chassis Bridge controller (CBC) on
the Legacy I/O board, and the Hot-Swap Controller (HSC) on the T-docking Board.
The firmware of the three microcontrollers are field upgradeable using the Firmware
Update utility. For information on the Firmware Update Utility, refer to “Upgrading
the Firmware” on page 98.
Baseboard Management Controller (BMC)
The Baseboard Management Controller (BMC) is a microcontroller with associated
circuitry that resides on the Legacy I/O board. The primary purpose of the BMC is to
autonomously monitor for system platform management events, and log their
