T520 2760QM, planning to install Intel IT-8260HMW-B, I saw somebody did this on reddit and there's one on aliexpress in half mini pci-e format.

I have tried the files uploaded by killer23d, which I thank you very much for!
Sadly it seems to crash on windows 10 1809 64 bit. It does a bluescreen with WinFlash64.sys, I figured to update winflash from asus, but it fails.
Ended up buying a 10$ 2.5" Seagate HDD and installed windows 7 32 bit on it, I had to move wifi drivers as there was no internet and no drivers at all.
No battery drivers, so winflash would stop flashing because it won't flash without battery plugged in and charging.
Sideloaded WiFi drivers, did all the updates in windows 7 and the drivers also downloaded along.
Battery was visible and I double click flash.bat, allow UAC and it goes smoothly. I also did battery firmware upgrade while at it, as this one also crashed on Windows 10 bit, bluescreen.
TL;DR
All went great, but there's 5 beeps, pause 5 beeps and then it boots
I found out a very old post that said to switch Security Chip to Inactive and it doesn't do this anymore.
This supposedly turns off the TPM. I was wondering if there's a chance of having 1.49 bios with working TPM?
Thanks everybody, this is truly a great device
