Seems like Intel should at least be able to tell us how to configure their BIOS correctly. Thanks for confirming the need for "disable XHCI" for USB. I tried a lot of things, so I don't remember what other setting I used for intial install. I thought I just used their document setting and had to go to XHCI disable to use my mouse.
Thanks for the info on the Realtek lan driver. But, I have abandoned Win7 pending the availability of better video drivers. I need 1920x1080 for my home theater. Please post here if you find a solution for that..
The software for this box is not ready for prime time. Except maybe for Win 8. I have not tried that.
I have gotten a Linux Mint 16/XBMC home theater configuration working with the big help of Jason Hoffman. See my other thread if you want to try that.
My main interest was having a browser on my TV.
