1.1.2 Technology

AGP (Accelerated Graphics Port)

The system board is equipped with 1 AGP slot. AGP is an interface

designed to support high performance 3D graphics cards. It utilizes a

dedicated pipeline to access system memory for texturing, z-buffering

and alpha blending; delivering up to 533MB/sec. bandwidth for 3D

graphics applications. AGP in this Pentium II processor based system

board will deliver faster and better graphics with your PC .

SDRAM (Synchronous Dynamic Random Access Memory)

The system board supports unbuffered SDRAM memory. SDRAM is

a DRAM technology that uses the clock on the chip to synchronize

with the CPU clock so that the timing of the memory chips and the

timing of the CPU are synchronized. This saves time during

transmission of data, subsequently increasing system performance.

Ultra DMA/33 Bus Master IDE

Synchronous Ultra DMA mode provides data transfer rate up to a

maximum of 33MB/sec, which is twice the data transfer rate of

Enhanced IDE or ATA-2. This enables the CPU to operate more

efficiently when handling simultaneous events.

P2XLX/e System Board Users Manual

ECC (Error Checking and Correction)

ECC is a function that allows the system to recover from memory

failure. It detects single-bit and multiple-bit errors and corrects single-

bit error thus providing uninterrupted processing of data. To use this

function, you must install DIMM that supports parity. Refer to

Installing System Memory in Chapter 2 of this manual.

ACPI (Advanced Configuration and Power Interface)

The system board is designed to meet the ACPI specification. ACPI

has energy saving features that enables PCs to implement Power

Management and Plug-and-Play with operating systems that support

OS Direct Power Management.
