I'm just interested in getting some direction here to know where to look next. I have a z77 pro, updated now from stock to the newest bios now. It comes with a wifi module that plugs into pins on the board itself (0C001-00050200). The deluxe version comes with a similar module, (0C011-00040100) but it adds bluetooth and wifi A. I bought this module, figuring that would be a good mod, adding bluetooth with the least trouble. I seem to be wrong about that. Wifi is seen by windows (7) and works fine. No device is seen in device manager for bluetooth however and attempts at installing bluetooth drivers fail with an inability to detect a bluetooth device. The only online guidance Ive seen after quite a bit of looking is; to get the bluetooth going you should enable it in the bios. The bios I had and the bios I upgraded to both have options to enable wifi, but not bluetooth. I went through the initial steps to installing the deluxe bios (same bios version number as my newest) to see if it was possible, but got a security verification error, so going that route wont necessarily be simple. So... on to the bios. Should I look further into cross flashing the bios to have a bluetooth option? As far as I can tell they are pretty much the same board, just with a very few differing options, and the base technologies are all there. There are different numbers of pci slots for example, not a complete lack of them. Anyone have any experience with this? Seen it done on these boards? Gotten the bluetooth to work on the pro version? Id like to hear about it. Thanks!
