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.
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
- 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?
