System Board

This chapter describes the system board and all its major components. It contains the
system board layout, jumper settings, cache and memory configurations, and
information on other internal devices.
The M25D system board is a PCI bus-based dual-processor system board built on an
extended ATX baseboard. It comes with a dual FC-PGA (Flip-Chip Pin Grip Array)
processor socket utilizing an Intel Pentium III processor integrated with the VIA Apollo
Pro 133A chipset. The system board also integrates the Intel 82559 10/100 Mbps PCI
Ethernet chipset that supports WOL (Wake on LAN) and provides for better remote site
management.
For expandability, the system board includes one AGP (Accelerated Graphics Port) bus,
five PCI bus slots, and three DIMM sockets that allow memory installation to a
maximum of 1.5 GB, using three 512-MB SDRAM (synchronous DRAM) DIMMs.
For connectivity, the system board supports two USB (Universal Serial Bus) connectors,
a speaker-out/line-out, audio-in, and microphone-in port, and other standard features
such as two UART NS16C550 serial ports, one enhanced parallel port with Enhanced
Parallel Port (EPP)/Extended Capabilities Port (ECP) support, a diskette drive interface,
and two embedded hard disk interfaces.
Only Linux, Windows NT 4.0, and Windows 2000 are supported by SGI.
The Pentium III processor implements dynamic execution performance, a
multi-transaction system bus, Intel MMX, and SSE instructions. Also, it offers streaming
SIMD (Single Instruction Multiple Data) extensions, which are 70 new instructions
