[Request] Asus K501UX Bios Unlock

[reload]

Hi guys,

I'm new to the forum so nice to meet you!
I'm trying to unlock advanced features on the bios of my Asus K501UX. In particular I need to enable Hot Plug for PCIe slots for my eGpu setup.

I've tried opening the bios dump with AMIBCP 4.55.0070. I open the file, I can see the settings and all, but cannot save due to an error of the visual studio c++ libraries.
I don't know if I have a problem with the installed libraries or if it's just a creative way the app is telling me that has crashed.
Can't find any newer version and older versions don't open the file.

I'm totally stuck, could you help me? Even if I can't unlock advanced settings It would be enough to have hot plug enabled on the pcie slot 6.

Thanks to anyone willing to help me

I'm attaching the dump of the bios taken with afuwin

A quick follow-up! 
I managed to save my modded bios, all I had to do was using AMIBCP v5 (which I didn't even know it exists).

Unfortunately, I couldn't make pci-configuration tab menus appear in the bios, but I managed to enable the hotplug setting it as a default. 
So my issue is solved, but can't really say I have unlocked the bios!

If anyone is interested just ask.

What did you do. I need to do this exact thing with an ASUS U57A. 

I looked up the program you mentioned but it doesn't seem to mentions Sandy Bridge, which is the type of CPU I have.

Thanks!
