Thanks for posting your query at this community forum.
I see you currently have installed Windows 8 on your computer. I know the latest chipset driver is already included as part of the operating system package. In other words, the chipset driver of the operating system comes with necessary drivers to support the Intel chipset on your system.
Please bear in mind the INF update utility does not contain SATA AHCI drivers. If you need SATA drivers, they are available through different download. The latest SATA drivers supported by your Intel chipset is version 10.1
Thank you so much for your prompt response. Is there any downside or benefits if i perform infinst_autol.exe -overall (the motive is just to have intel named in drivers details rather than MS)
Also the target device mentioned in the OEM intel chipset s/w is 965m and for the one in the infinst_autol.exe is 8 series chipset. Or the latest inf update utility contains all the required infs for the 965m also.
Does the OEM tweak anything inside chipset infs..
Also when i install inf update it is wiping out iastor.sys with storio.sys so does it wipe out already installed drivers.
Thank you for getting back to our community. If you run the latest INF utility with a fresh operating system installation, it will update any Microsoft generic driver.
I know Original Equipment Manufacturer (OEM) drivers can be modified according to your computer manufacturer and system design.
The latest chipset utility will contain all require INF for your chipset model.
Again, the INF update does not make any changes to iastor.sys.
