The PCI bus defines two types of data transmission modes: posted and non-posted. Bus transactions using posted data transmission are also called posted bus transactions, while bus transactions using non-posted data transmission are also called non-posted bus transactions.

For example, the main menu is displayed on the left, with the outer Expander. Each unit in the content contains a TreeView. The structure of each item in the TreeView is the display icon on the left and the text title on the right, you can double-click to open the interface of the function. This is common. However, it is required that the module can be

Computer files have their own suffix names. Files of the same suffix name can be considered as a type of file. Files with the same suffix name can be opened in the same way. When you encounter a problem, you can query the file suffix name to determine whether the same preliminary problem.

disable the lnka device, The ACPI Specification defines that the OS must execute the _ dis function of the device. From the hardware point of view, to disable the lnka device, you need to set the maximum position of the configuration space register of a PCI device to 0 × 60. The OS does not need to know the hardware details. It just needs to explain and execute the _ dis function. The above code is the AML code, provided by the bios, with the 'or (\
