    What do INF files do?

    RJSmith92

      Hello,

       

      I understand that Windows uses INF files so that the correct name is show in Device Manager but I was reading the following 'Read Me' text for the 'INF Update Utility' and it says the following -

       

      "The Intel(R) Chipset Device Software installs Windows*

      INF files to the target system. These files outline to

      the operating system how to configure the Intel(R) chipset

      components in order to ensure that the following features

      function properly:

       

        - Core PCI and ISAPNP Services

        - PCIe Support

        - IDE/ATA33/ATA66/ATA100 Storage Support

        - SATA Storage Support

        - USB Support

       

      Do the INF files really provide anything for things listed above? All of these work with the generic INF files that Windows provides without installing any INF files from Intel.

       

      Any clarification would be appreciated,

       

      Thanks.

          Hello RJSmith92, is your question strictly related to Chipset INF files?

          Usually Microsoft* inbox drivers provide basic functionality; so, I would think such drivers support the same features for a chipset component but that is something that only Microsoft* can answer. Other device drivers for different hardware (other than chipset) may contain INF files too, but the features will differ from the ones expressed above.

            Thanks Joe,

             

            Yes it's really just regarding chipset INF files. The Intel® Chipset Device Software (INF Update Utility) says that it -

             

            "The Intel(R) Chipset Device Software installs Windows*

            INF files to the target system. These files outline to

            the operating system how to configure the Intel(R) chipset

            components in order to ensure that the following features

            function properly:

             

              - Core PCI and ISAPNP Services

              - PCIe Support

              - IDE/ATA33/ATA66/ATA100 Storage Support

              - SATA Storage Support

              - USB Support

             

            But my point is do the INF file provided by Intel really do what it says above. What is in the INF files that Windows uses to configure the chipset correctly? is it just to make sure Windows runs the correct bus driver for each chipset component?

             

            Thanks.

              The Intel® Chipset Device Software does what it says above. In regards of Microsoft* inbox INF files, I would expect basic functionality but for more detailed information I suggest asking Microsoft*.
