System Board

The V65XA-2 is an all-in-one high-performance system board that
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 also comes in the same
package but without second-level cache. Both are capable of handling
multimedia functions and enhancing the performance of 32-bit
applications.
The system board memory is upgradable to 256 MB via two 168-pin
DIMM (Double In-line Memory Module) sockets.
The board
incorporates a 3-D video controller with AGP (Accelerated Graphics
Port) feature, 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 two UART
(Universal Asynchronous Receiver-Transmitter) 16C550 serial ports, 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) slot, one PCI-/ISA-shared slot, and three PCI (Peripheral
Component Interface) slots.

  • Page 8: Installation Precautions

    Installation Precautions Before you install any system component, we recommend that you read the following sections. These sections contain important ESD precautions, pre- and post-installation instructions. 1.4.1 ESD Precautions Electrostatic discharge (ESD) can damage your processor, disk drives, expansion boards, and other components. following precautions before you install a system component: Do not remove a component from its protective packaging until you are ready to install it.
  • Page 9: Post-Installation Instructions

    Do not attempt the procedures described in the following sections unless you are a qualified service technician. 1.4.3 Post-installation Instructions Observe the following after installing a system component: See to it that the components are installed according to the step- by-step instructions in their respective sections.
  • Page 10: Memory Configurations

    Memory Configurations The system board comes with two 168-pin DIMM sockets that allow you to expand memory to a maximum of 256 MB. The DIMM sockets support SDRAMs (Synchronous Direct Random Access Memory) and EDO (Extended Data Out) DRAMs with 16-, 32-, 64-, and 128-MB capacities, 60 ns (nanoseconds) or less access time, and without ECC feature.

    1.5.2 Removing a DIMM To remove a DIMM: Press the holding clips on both sides of the socket outward to release the DIMM. Gently pull the DIMM out of the socket. Figure 1-4 Removing a DIMM 1.5.3 Reconfiguring the System The system automatically detects the amount of memory installed.
  • Page 13: Upgrading The Processor

    Upgrading the Processor The board supports a Pentium II processor or a Celeron processor. Both processors come in a new enclosed packaging technology called S.E.C. (Single-Edge Contact) cartridge. The only difference between the two is that the Pentium II processor comes with 256-KB or 512-KB built-in second-level cache, while the Celeron processor comes only with an internal cache.
