As to the files in the package....
>
.inf files are driver install/instruction files. You can open them to see them yourself using Notepad (tho they'll probably still look very cryptic!). They contain the specifications and instructions Windows uses to understand which driver it should match with particular hardware ('cuz Windows will find many, many different drivers stored on your computer and it must choose from) It also contains any driver specific instructions needed to help Windows install the
.sys driver file
>
.cat files contain Windows security and file info data. Not completely sure about everything that's in these file extensions but, in part, they would contain the digital signatures for signed files
>
textsetup.oem file is used to instruct Windows at installation setup time to add/load your SATA drivers (e.g. when you hit F6 to add new drivers to the installation)
Which begs the question.. just what did you point Windows device manager to when you installed the iastor.sys driver using device manager. Typically, for example, when prompted by
New Hardware Wizard you must point to the correct
.inf file.... Or maybe you just told Windows to include the package folder when scanning for suitable drivers?
When i look in
.inf files for the package you downloaded i can see a version (below). I assume this is the version info you now see installed, yes?
