Appendix C. Customizing the device-driver configuration settings

Windows Me has two device-driver configuration parameters: Auto Insert Notify and DMA.

The Auto Insert Notify parameter enables the computer to start playing or accessing the disc automatically after being inserted in the drive.

The DMA parameter improves computer performance by having the computer DMA controller handle data transfers from the CD to memory, freeing the computer microprocessor to perform more important tasks. For example, activating DMA might make movies and games run more smoothly because the microprocessor will be allocating more processing time to video.

Enabling DMA for Windows Me

To change the DMA parameter settings from the Windows Me desktop, do the following:

1.Click Start --> Settings --> Control Panel.

2.Click on view all control panel options.

3.Double-click System.

4.Click the Device Manager tab.

5.Double-click CD-ROM.

6.Click on the drive that you want to modify.

7.Click the Settings tab.

8.Click to select the DMA check box.

9.Click OK.

Enabling DMA for Windows 2000

To change the DMA parameter setting for Windows 2000, do the following:

1.Click Start --> Settings --> Control Panel.

2.Double-click System.

3.Click the Hardware tab.

4.Click Device Manager.

5.Click the IDE ATA/ATAPI controller to open up the tree.

6.Double-click the device that corresponds to your CD-ROM port. It is either Primary IDE or Secondary IDE.

7.Click the Advanced Settings tab.

8.Click the Transfer Mode menu and select DMA if available.

9.Click OK.

22P6975 specifications

The IBM 22P6975 is a crucial component within the IBM information technology ecosystem, specifically designed to enhance the capabilities of IBM servers. It is a high-performance memory module that plays a significant role in improving overall system efficiency, reliability, and speed. Particularly, it is built to fit into IBM System x and BladeCenter systems, making it a versatile option for various configurations.

One of the standout features of the IBM 22P6975 is its DDR3 SDRAM technology. DDR3 memory is known for its data transfer rates and reduced power consumption compared to its predecessors. The 22P6975 operates at a speed of 1333 MHz, although it can also support speeds up to 1600 MHz, providing an efficient solution for demanding server applications. Its architecture supports improved bandwidth and lower latency, which are vital for performance-intensive tasks.

In terms of capacity, the IBM 22P6975 typically comes with a size of 4GB, allowing for ample memory space for running multiple applications and services simultaneously. The module is designed with a 240-pin DIMM form factor, making it easily installable in compatible server systems. The Registered ECC (Error-Correcting Code) feature is another significant advantage, as it enhances data integrity by detecting and correcting internal data corruption, thus ensuring maximum uptime and reliability for critical applications.

The memory module is also designed with thermal management in mind. It operates efficiently within a wide range of temperatures, making it suitable for enterprise environments where reliability is paramount. The IBM 22P6975 adheres to stringent industry standards and provides backward compatibility with earlier memory technologies, ensuring businesses can upgrade their systems without having to overhaul existing infrastructure.

Furthermore, the 22P6975 is part of IBM's commitment to sustainability, as it operates at lower power levels, which reduces energy consumption and operational costs. This feature not only benefits the environment but also contributes to the overall cost-effectiveness of maintaining a data center.

In summary, the IBM 22P6975 memory module is characterized by its advanced DDR3 technology, substantial memory capacity, ECC capabilities, and energy-efficient operation. It is an integral part of IBM's server solutions, delivering reliability and performance for businesses that require robust IT infrastructure. This module is a valuable investment for any organization looking to enhance their computing capabilities while ensuring data integrity and system reliability.
