Hi,
I have an issue with a 7710 motherboard, nor Wifi card/slot (8260AC and 3160AC) and LTE modem/slot (EM7455) are detected in bios/OS, the strange thing is that the wifi card is a wifi/bt combo and the BT is recognized in bios and working.
Since BT is working I think the power for these card is present, I already tried a few bios for the motherboard (asked on another thread) but only one is working, I got the board with a bricked bios and it's not a thunderbolt version.
I believe there is either a signal that disable the M.2 slot (all enabled in bios) or wireless capability or it's an issue with the PCIE signal the wifi and the modem are using.
For now I checked the common signal between both "non working pcie" slot which is SUSCLK and is present at 33.3kHz. There is also signal like PCIE_WAKE# or PCH_PLTRST#_EC but these are also used for the M.2 2280 slot and both M.2 2280 slot are working in sata or PCIE mode so this should works...
On the wifi slot there are some signal like m0375 or m0060 that are connected to the EC trough a diode, the LTE slot also have similar signal but they aren't common signal for both slot.
I also thought that they might have been disabled by the EC BUT I don't think the EC would mess with them when going into bios (I believe the EC should "enable" them in order to see them in bios).
Any help is appreciated, I don't really know the logic of the M.2 disabled/enable pin, should they be high or low. I don't if disabled, they should still being detected by bios and so on. I don't mind permanently enable both slot if possible.
Thanks for the help, please notes that the real board doesn't have the "UZ29" even present/written on the board.
