Hello people!

What happened
I had a crash with my laptop and now I have to reinstall video BIOS (vBIOS) to my graphic card.

What am I searching for
I'm trying to find video BIOS (firmware) for my NVIDIA 840M. I know, that this graphic card is quite old, but may be someone here has that graphic card and will be able to help me. All I need is just a vBIOS file.

What I tried
* Contacted ASUS support, no success. They said, that they don't have firmware files and can't help me.
* Contacted NVIDIA support, no success. They said, that I should contact ASUS.
* Searched video BIOS file at https://www.techpowerup.com/vgabios/, most likely, no success. May be someone can help me with that, but I didn't find anything so far.
* Contacted a guy from https://www.techpowerup.com/forums/threads/gt-840m-bios-file.249228/#post-3960766 topic, no success.
* Googled a lot - forums, sites, etc.

The repair center, which is repairing my laptop right now, didn't find the proper firmware (video BIOS) for my video card. Moreover, they tried to install 820M vBIOS without success. Sadly enough, without proper firmware my graphic card won't work at all. On top of that, I had a really bad crash - that's why repair center couldn't make a copy of my previous firmware.

Laptop spec
ASUS X751LN, Intel® Core™ i7 4510U Processor, NVIDIA® GeForce® GT 840M 2GB DDR3 (more at https://www.asus.com/Laptops/X751LN/specifications/).

There is one inside the bios file... download it from asus site.

Basically if there is no BIOS IC on the MXM card itself this option rom kicks in... it's been like that for a while.

And yes it is it... bios editor treats it fine.

I do not have the original VBIOS from your Asus, but I have a VBIOS from MSI:

Notebook MSI GP60 2PE (MS-16GH)
NVIDIA GeForce 840M, 2GB DDR3
VBIOS version: 82.08.17.00.0E

Graphic layouts are the same, so it's probably worth a try.

@Ferrum Master thank you for your reply! Well, just for clarify, it's not possible to install only VGA BIOS and I just have to install BIOS file, which contains VGA BIOS. OK, sounds good!
@cartonaudio thanks! I'll try to install original BIOS, but thank you - I see you just registered here to send me the reply, I really appreciate it.
