But, you will not find much.
What OS are you using? If Windows 10, all the driver should be "inbox".
IDSA will not work on discontinued Intel boards. All part of the IDSA "exclusion" list.
I have three 8-series and one 7-series board, and IDSA does nothing on any of them.
I have some of the files you might need, I kept all drivers for my boards. I really like the Intel DQ77NK as well as the DQ77KB. I saved all my drivers and such on my server for all my hardware. The question is how do you want me to get them to you? It looks like I have all BIOS updates, RST, STORWin7, MEI, LAN, Graphics Win 7 , and TechProdSpecs.
Documents you requested attached. As for drivers, what packages do you need and for what Windows version(s)?
[Hint: for Windows 10, most required drivers for 8 Series and earlier boards are built into Windows. You only need a very few (GFX, RST).]
Yes, we know Intel removed the drivers for each desktop board last year. However, many drivers still exist if you search specifically for them.
Now, you know that W7, as well as your board, is discontinued. Have you even installed W7 to see which drivers are missing? I know, you have an application that will only run on W7.
Since you will not provide the information, nor have you specifically identified the board in question (there were two mentioned in this old thread that you jumped on), go here and search: https://rebyte.me/en/intel/
