Anleitung Zusammenfassung


For help on hardware conflicts: 1 Click Start, then click Help and Support. 2 Click the Hardware link in the window’s left pane. A list of category links appear. 3 Click the Fixing a hardware problem link. 4 Choose from specific topics and follow the steps. If there is still a problem, the operating system should display a message that explains what the conflict is. A plan of action The smooth operation of the system depends on the interaction of all devices, programs, and features. If the system or one of its attached devices is not working, resolving the problem can be time-consuming and frustrating. The recommended procedure for getting multiple devices to work together is to add and set up one device at a time. After you add each device, test it to make sure it and all previously connected devices work. The device most recently connected to the system is the one most likely to be causing a hardware conflict. If Something Goes Wrong If Something Goes Wrong Resolving a hardware conflict Resolving hardware conflicts on your own Computer components need resources to accomplish a task. A device, such as a disk drive or a modem, needs a channel to the computer’s Central Processing Unit (CPU). It also needs a direct channel to the computer’s memory to store information as it works. These channels of communication are commonly referred to as system resources. Interrupt Request Channel The channel to the CPU is called an Interrupt Request (IRQ) because it interrupts what the processor is doing and requests some of the processor’s time. If two or more devices use the same IRQ, the processor does not know which device is asking for attention. This causes 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 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. Plug in the device and turn on your computer. The operating system is automatically set up to accommodate the new device. If Something Goes Wrong If Something Goes Wrong Resolving a hardware conflict If you install an older (legacy) device that the operating system cannot recognize, the operating system may have difficulty a...
