Network Controller

The system board includes a 10BASE-T/100BASE-TX network controller based on the Intel 82559 Fast Ethernet PCI Bus Controller. As a PCI bus master, the controller can burst data at up to 132 MB/sec. The controller contains two receive and transmit FIFO buffers that prevent data overruns or underruns while waiting for access to the PCI bus. The controller has the following:

!32-bit PCI bus master interface (direct drive of bus), compatible with PCI Bus Specification, Revision 2.1

!Chained memory structure with improved dynamic transmit chaining for enhanced performance

!Programmable transmit threshold for improved bus utilization

!Early receive interrupt for concurrent processing of receive data

!On-chip counters for network management

!Autodetect and autoswitching for 10 or 100 Mbps network speeds

!Support for both 10 Mbps and 100 Mbps networks, capable of full or half duplex, with back-to-back transmit at 100 Mbps

!Support for Wake On LAN.

SCSI Controller

The system I/O board includes an embedded Adaptec AIC7899 dual function SCSI controller. The AIC7899 provides two Ultra 160/m SCSI interfaces as two independent SCSI functions. As implemented on the system I/O board, channel A has one connection to the external connector on the rear of the chassis and another connection to the 5.25-inch devices in the removable media bays. Channel B is connected to the SCSI backpanel that supports up to two Ultra 160/m SCA drives unless the optional RAID controller is installed.

Video Controller

The system has an integrated ATI Rage IIC 64 bit high-performance SVGA subsystem that supports the following:

!BIOS compatibility with VGA, EGA, CGA, Hercules Graphics, and MDA

!4 MB of 10 ns onboard Synchronous Graphics Memory (SGRAM)

!Pixel resolutions up to 1280 X 1024

!Analog VGA monitors (single and multiple frequency, interlaced and noninterlaced) with a maximum vertical retrace noninterlaced frequency of 100 Hz.
