About which files are the real drivers. I'm not 100% up to date on this but I believe .inf is an install file for the driver and .sys files are part of the driver as well as any other .dll files and sometimes other files. The .inf file list a number of things including matching Hardware ID's, the required files to copy (.sys, .dll), reg entries and the Device Description that shows in Device Manager.
For example if you required the drivers to complete the steps in "How to Load SATA Driver in Windows 7 setup" you would download the latest "Intel(R) Rapid Storage Technology" driver and extract it. Open the folder and browse to "\Driver\64bit" (or "32bit" if you had a 32bit Windows). Then copy all the files except the 2 .txt files to a floppy, CD/DVD or USB. You shouldn't have to copy the iaAHCI files really unless your SATA mode in the BIOS is configured as AHCI. The txtsetup.oem is only required for this type of install and the .cat files I'm not sure but you need them. This will only install the driver and not the software that comes with it.
For your LAN driver you would find the required files in "\Win 7\64" (without space) or "\RIS\64". If you don't know what RIS is then you don't need them, you only need one of the folders and I'm 99% sure it won't be RIS. Do you need both the .sys and .dll file, who cares keep them all together and you can't go wrong, you could go through the .inf to find out but thats not always easy and not necessary. You won't be able to install the LAN driver the same way as your SATA above.
Other people please correct me if I'm wrong, I would hate to have given any wrong info.
Hi All,
Had exactly the Same Question as Beekof regarding exactly which files (extension) the Device Drivers are?
Duzzy Seems to have covered the question pretty well (PP Quote above & thanks) but thought I would add the following after having done a little research!!
When Installing windows 7 and after clicking on the CUSTOM install, you get a option to "Load Driver" at bottom left of the dialog box. Clicking on it takes you to another Dialog Box and you need to supply the Device Driver, that is navigate to where the Device Driver/Drivers are!! This, from what I can figure out, is the FOLDER Containing the Device Drivers. The Device Drivers are actually made up of AT LEAST twp (2) file's. One with a ".inf" the other a ".cat" extension. The ".inf" file is actually a text format file containing information about the manufacturer, the specific device etc etc -
IT's a Infomation file!
The ".Cat" would contain (
I'm NOT 100% Sure) other info such as registry keys etc to be set in the Registry.
IN A NUTSHELL, Locating a Device Driver is a matter of finding the ".inf" & ".cat" file's in a Folder such as "Win_7" or "x64". Once Selected the "Load Driver" pass the Source back to the Windows 7 Installer which then installs the Device Driver by finding ANY ".inf" files!
I managed to find the following "
Working with Setup Information (.inf) Files" (Click on Link) which explains a lot.
I'm NOT SURE if you can say Install your ChipSet Drivers & then go back and Load additional Drivers (SATA, LAN etc) individually by selecting a different folder each time OR maybe you can setup a Folder with sub folders containing each set of drivers. EG $Drivers$/Chipset - $Drivers$/SATA - $Drivers$/LAN. Then if you Select the "$Drivers$" Folder will the "Load Driver" find the Sub folders??? Hopefully some will know the answer to that One.
Thanks to all who have contributed and hope the above help's others!
