Chapter 2
This chapter describes the system board and all of 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
Intel Celeron processor with MMX technology. The Pentium II processor comes in a modular design with an
integrated 512 KB second-level cache. The Celeron processor is Intel's entry-level Pentium II solution, and comes
without or with a 128 KB second-level cache. Both the Pentium II and Celeron processors 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 16-, 32-, 64- and 128 MB DIMMs.
The board also incorporates a 3D video controller with AGP (Accelerated Graphics Port), 4 MB SGRAM
(Synchronous Graphics Random Access Memory), and a 3D audio controller to fully support multimedia functions.
Onboard I/O (input/output) interfaces are comprised of a UART (Universal Asynchronous Receiver-Transmitter)
16C550 compatible 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.
Special features such as PnP (Plug-and-Play) support, Power Management, Wireless Communication, Hardware
Monitoring, Wake-on Ring, and Wake-on LAN (Local Area Network) functions are also supported. These
functions are individually discussed in this chapter.
