System Overview 1-19
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 board includes an embedded Adaptec AIC7880 SCSI controller and an
Adaptec AIC7899 dual function SCSI controller. The AIC7880 provides one Ultra-
Wide SCSI device interface and the AIC7899 provides two Ultra160/m SCSI interfaces
as two independent SCSI functions. As implemented on the system board, the AIC7880
Ultra-Wide channel 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 A of the AIC7899 controller is connected to the SCSI backpanel associated
with the standard SCSI hard disk drive bays that supports up to five Ultra160/m SCA
hard disk drives.. Channel B of the AIC7899 controller is connected to the SCSI
backpanel associated with the optional SCSI hard disk drive bays that supports up to
five Ultra160/m SCA hard disk drives.
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.
