Pnp os installed

The following Enum information is listed for debugging purposes only. An enumerator is a component that discovers PnP devices based on a PnP hardware standard.

The tasks of an enumerator are carried out by a PnP bus driver in partnership with the PnP manager. Some devices are enumerated by a bus filter driver, such as ACPI. If Capabilities. If not, the PnP manager modifies the ID so that it is unique system-wide. At this point, the PnP manager is ready to locate the function driver and filter drivers for the device, if any. See the following figure. The kernel-mode PnP manager coordinates with the user-mode PnP manager and user-mode Setup components to find the function and filter drivers for the device, if there are any.

The kernel-mode PnP manager queues an event to the user-mode PnP manager, identifying a device that needs to be installed. Once a privileged user logs in, the user-mode components proceed with finding drivers. See the device installation overview For information about Setup components and their role in installing a device. The user-mode Setup components direct the kernel-mode PnP manager to load the function and filter drivers.

The user-mode components call back to kernel mode to get the drivers loaded, causing their AddDevice routines to be called. The following figure shows the PnP manager loading the drivers if appropriate , calling their AddDevice routines, and directing the drivers to start the device. Before the function driver attaches to the device stack, the PnP manager processes any lower-filter drivers.

For each lower-filter driver, the PnP manager calls the driver's DriverEntry routine if the driver is not yet loaded. Then the PnP manager calls the driver's AddDevice routine. Once it attaches its device object to the device stack, the driver is engaged as a driver for the device. Dec 22, 0 0. Linux needs it to be no. I would leave it like that anyway though.

Windows is a different story. Feb 6, 0 0. I've always had it at NO. The Sauce Diamond Member. Oct 31, 4, 34 Unless you are having IRQ problems, the answer is no Jun 3, 3, 0 0. I always use NO. And it works perfectly. Jan 6, 14, 0 I always say no even though windows is PnP! Jan 4, 1, 1 No for me works fine dual boot linux and win me of course yes works for me too Mem Lifer. Apr 23, 21, 13 Therefore, it is recommended that you set this feature to No , to allow the BIOS to configure all devices.

It actually does not matter what setting you select. There is no longer a need to specifically split the job up between the BIOS and the operating system. However, there is an additional catch to it. Certain operating systems i. Windows 98 and above will only access the buggy BIOS in read-only mode. This means the operating system will rely entirely on the BIOS to configure all devices and provide it with the hardware configuration.

Setting the system to PnP OS says that even if the machine determines some kind of resource problem, it should not attempt to handle it… Rather, it should pass it on to the OS to resolve the issue. This allows the operating system some flexibility in shuffling system resources like IRQs and IO ports to avoid conflicts.

It also gives you some degree of freedom when you want to manually assign system resources. If you are using an ACPI-compliant operating system i. If there is no need to configure any hardware manually, it is again recommended that you set this feature to No. The solution?
