Bios Mods -The Best BIOS Update and Modification Source

Hello, I have a Dell 7720 R17 SE which had a 3630qm, but I upgraded it to a 3840qm without problems. Does anybody have an unlocked BIOS?
It's a nice laptop for OSx86, even if the nVidia doesn't work because of the Optimus system. I have some minor problems left, maybe an unlocked BIOS can help.

Here's the link to the A17 BIOS: https://dl.dell.com/FOLDER03028974M/1/7720A17.exe

Hi all,

I want to unlock the BIOS of my Dell Inspiron 17R SE 7720, mainly to disable HyperThreading and to manage some advanced BIOS settings.
All online BIOS I found are old and/or link are broken.

I can try to mod it myself if someone can explain what to look in the BIOS file

Here's the BIOS A17 (EXE and CAP files): https: //easyupload-DOT-io/6azcdf

I didn't do it for you. I do not know how to open additional menus in such bios, so I repeated the first mod in this thread, but just for version A17: read about MSR lock and AES NI.

Didn't expected that you did that for me. I was just asking.
Anyway the A12 modded is working fine even if I have the i7-3630QM. I disabled the HT successfully.
Now I need a manual or something like that, because the CPU isn't throttling (it stays at max speed indicated in the Power Options of Windows) and I want to see if I can power up the fan (it goes at maximum speed only when upgrading bios, CPU/GPU go at 90°C and it won't go full throttle) and do something about the Nvidia GPU (nvidia Inspector overclock is not sufficient).

Thank you for the reupload of the A12 unlocked BIOS

Works flawlessly:
