Default Alienware 17R2 BIOS chip location

Hi there, this is my first post, just hope it is in the right spot.

I have an Alienware 17R2 whose motherboard is LA-B753P. I downloaded the latest BIOS file from Dell website and now it is bricked. I googled everywhere and it seemed to use a programmer to reflash BIOS is the only way (and the cheapest way) to solve the issue.

So my question is: is there anyone who can tell me where is the location of BIOS chip location? I know it is a little silly but from the pictures I found through Google, it seemed that there are more than one 8-pin chips on the motherboard, one is close to the killer wifi card and another one is close to CMOS battery. Really appreciate if anyone can let me know which is the right one to reflash.

I tried both, but, unfortunately, neither is working on my laptop. I think it is totally dead

Oh Thank you so much Mazorca. It is good to know UH4 is the right one so that I don't need to pull the whole motherboard out. Thanks!
