The following table contains information about the Silicon Graphics
320 visual workstation system board ports and buses.
Table A-3 System Board Specifications
Port or Bus Description
Processor bus One or two Intel Pentium II Slot 1 processors with
100 MHz Front Side Bus (FSB). Dual processor
systems must have both processors at the same
frequency. Uniprocessor systems must have a
terminator module in the second processor slot.
Memory
configuration The minimum memory configuration is 128 MB using
six 4 M x 48 DIMM modules. The maximum memory
configuration is 1GB using 12 16 M x 48 DIMM
modules. DIMMs must be added in groups of six.
Ultra DMA IDE One UltraDMA/33 IDE channel for one internal
3.5" x 1" system drive and one internal option 3.5" x 1"
disk drive.
Ultra DMA IDE One UltraDMA/33 IDE channel for 5.25" x 1.6" CD or
DVD drive and one optional 3.5" x 1" removable
media drive.
FDI One Floppy Drive Interface for a 3.5" x 1" floppy drive.
USB Two Universal Serial Bus (USB) ports.
Monitor port VGA connector to CRT or analog-interface flat panel
monitor. Supports monitor ID and control via DDC2B
interface.
Display option One optional digital interface connector flat panel
monitor port supporting the Silicon Graphics 1600SW
flat panel monitor.
IEEE 1394 port Two IEEE 1394 connectors at 400 Mbps.
Serial port One RS-232 serial port with separate DMA channels
for input and output. Each channel is capable of up to
115 Kbaud and is full duplex.
