Driver Rank Example
List of hardware IDs
List of compatible IDs
CID_1, and CID_2
The first hardware ID in a list of hardware IDs is the most specific identifier for the device. In this example, that is HwID_1.
Also assume there is an INF file that has an INF Models section that has the following entry, where the INF_XXX_N names represent actual hardware IDs and compatible IDs:
DeviceDesc1 = InstallSection1, INF_HWID_1, INF_CID_1, INF_CID_2
In addition, assume that the INF DDInstall section named InstallSection1 has the following FeatureScore directive, where the corresponding feature score of the driver is 0x00GG0000:
The following table lists the rank of each possible match between the identifiers that are reported by the device and the identifiers that are listed in the INF Models section entry. The rank is the sum of the signature score, which is represented by 0xSS000000, the feature score, which is represented by 0x00GG0000, and the identifier score, which depends, in each case, on the two identifiers that matched.
