195 If Something Goes Wrong Resolving a hardware conflict Direct Memory Access Similarly, the data required by the device is stored in a specific place or address in memory called the Direct Memory Access (DMA). The DMA provides a dedicated channel for adapter cards to bypass the microprocessor and access memory directly. If two or more devices use the same DMA, the data required by one device overwrites the data required by the other, causing a hardware conflict. Plug and Play With Plug and Play and the Windows® operating system, avoiding hardware conflicts is easy. Plug and Play is a computer standard that helps the system BIOS (basic input/output system) and the operating system to automatically assign system resources to Plug and Play-compliant devices. In theory, if every device connected to the computer is Plug and Play-compliant, no two devices will compete for the same system resources. You simply plug in the device and turn on your computer. Your operating system automatically configures your system to accommodate the new device. However, if you install an older (legacy) device that the operating system cannot detect, it may have difficulty assigning system resources to it. As a result, a hardware conflict can occur. To find out what resources are assigned to the legacy device, refer to the section "Checking device properties." Checking device properties Device Manager provides a way to view the properties of a device. Properties include the name of the manufacturer, the type of device, the drivers installed, and the system resources assigned to the device. To check a device's properties: 1 Click Start, then point to Settings, and click Control Panel.
