System Board

The V72MA is a high-performance system board that supports the Pentium processor with MMX (MultiMedia eXtensions) technology. The MMX feature enables the system to handle multimedia functions and enhance the performance of 32-bit applications.

The system memory is upgradeable to 256 MB via the onboard two 168-pin DIMM (Double In-line Memory Module) sockets. These sockets accommodate 8-, 16-, 32-, 64- and 128-MB DIMMs. The system board may also come with either 0 or 512-KB second-level cache.

To fully support multimedia functions, the board incorporates a highperformance 3-D video controller with AGP (Accelerated Graphics Port) feature, 4-MB SGRAM (Synchronous Graphics Random Access Memory), and a 3-D audio controller.

Onboard I/O (input/output) interfaces are comprised of two UART (Universal Asynchronous Receiver-Transmitter) 16C550 serial interfaces (one port and one connector), 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 Microphonein port, one 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 one ISA (Industry Standard Architecture) slot and three PCI (Peripheral Component Interface) slots.

System Board 1-1

Special features such as PnP (Plug-and-Play) support, Power Management, Wireless Communication, Hardware Monitoring, Modem Ring-in, and Wake-on LAN (Local Area Network) functions are also supported. These functions are individually discussed in this chapter.

The system is fully compatible with MS-DOS V6.X, OS/2, SCO UNIX, Windows NT, and Windows 95/98 operating systems.
