Chapter 2 System Board
This chapter describes the system board and all its major components, including:
Details about the system board layout
Jumper and connector locations and functions
Jumper settings
The system board supports the Intel Pentium II processor with MMX (MultiMedia
eXtensions) technology and the Celeron processor. The Pentium II comes in a card
design with 512-KB second-level cache already integrated. The Celeron processor is
Intel's Pentium II cost-down solution. It comes without or with 128-KB second-level
cache. Both are capable of handling multimedia functions and enhancing the
performance of 32-bit applications.
The system memory is upgradable to 256 MB via the two onboard 168-pin DIMM
(Double In-line Memory Module) sockets. These sockets accommodate 8-, 16-, 32-, 64-
and 128-MB DIMMs.
The board also incorporates a 3-D video controller with AGP (Accelerated Graphics Port),
4-MB SGRAM (Synchronous Graphics Random Access Memory), and a 3-D audio
controller to fully support multimedia functions.
Onboard I/O (input/output) interfaces are comprised of a UART (Universal Asynchronous
Receiver-Transmitter) 16C550 serial port, a parallel port with SPP (Standard Parallel
Port)/ECP (Extended Capabilities Port)/EPP (Enhanced Parallel Port) support, and PS/2
keyboard and mouse ports. Two USB (Universal Serial Bus) ports, one VGA (Video
Graphics Accelerator) port, one Feature connector, one mono Microphone-in port, one
stereo Line-in port, one Line-out port, and one Game/MIDI (Musical Instrument Digital
Interface) port are also added to the board design to enable the system to support
additional peripherals.
For expansion, the board comes with two PCI (Peripheral Component Interface) slots.
