There are a number of very important steps that need to be carried out to ensure your platform is running at top speed. This site has been designed for Resellers, Integrators, and experienced PC users to achieve & experience the power of the Intel® Celeron D processor in the 478 pin package. These advanced techniques are intended for professionals experienced with integration of personal computers, peripherals, operating systems, and drivers.

Installation Order
Correct Driver installation is crucial to overall platform performance. Drivers should always be installed in the order displayed in Table 1 below. The most critical step in the installation order is to run the Intel® Chipset Software Installation Utility before all other drivers. Once the chipset is properly detected and configured using this utility, device driver installation order becomes less crucial and will have less impact on system performance.

Driver Descriptions

• Intel® Chipset Software Installation Utility
  The Intel Chipset Software Installation Utility is a driver that enables features of the chipset that are built into the motherboard. This utility must be installed FIRST in order for the operating system to accurately use the features built into the chipset. If this utility is not installed, the operating system may not know what chipset is being used and may not run to full potential.
  
  One important chipset feature that will be left disabled if the chipset utility is not installed correctly is the AGP bridge. The AGP bridge is built into the Memory Controller Hub of the chipset and is responsible for routing communications between the motherboard and the AGP graphics card. If the bridge is not enabled, overall graphic performance of the platform will be compromised.

• Microsoft DirectX* 8.1 (or later)
  Microsoft DirectX 8.1 supports Streaming SIMD Instructions 2 (SSE2) for the processor and is not included in the latest Microsoft operating systems. This version of DirectX is not included in Microsoft operating systems. A system that does not have DirectX 8.1 installed will not be able to take advantage of the 144 new SSE2 processor instructions that are supported by the Intel® Celeron® D processor. Neglecting to update DirectX can reduce your system performance.
