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 V65MA 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 256- or 512-KB second-level cache already integrated.
The Celeron processor is Intel's Pentium II cost-down solution. It comes without
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), 2- or 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 ISA (Industry Standard Architecture)
slots and two PCI (Peripheral Component Interface) slots.
