ASUS r900vb bricked bios !

[gubenena]

Hello all in advance and thanks for all the help...


Asus r900vb, motherboard zay90 la-a681p.
Problem is that my brother in law somehow flashed for his known reasons bios to the latest from asus web site, K95VBAS.209....
Now I think he corrupted his bios flashing it either trough USB 3.0, or something else went wrong black screen on post...
It surely works and everything fires up....But no screen...

I own EN25T80 and I use CH341A software...Since it's been a long time ago I used my programmer, forgetting thing seems irrelevant , can you please help me out on this...

Downloaded bios file from asus web site is in .208  .209  formats. I did make a backup from the chip itself and it's somewhere around 8mb file.... Downloaded file is around 4mb.....
What am I missing....
When I try to load the file to ch341a software since it;s not a .bin. file it simply does not recognize it... Should I just rename the file to .bin. or am I suppose to somehow convert the file to .bin.
Seems there is a trick with thees new UEFI bioses or am again to old and did not follow a build up of new upcoming bioses...

I'm worried about difference in file size between the one I backed up from chip and the one I downloaded from site.....
What am I missing .... Thanks guys....
Chip is winbond 25q64fvsig.

And ya I read something about flashing bios-es with programmer you actually loose or of data about mac address etc...
Can someone with more knowledge instruct me what am I suppose to do or just link me to step by step hard flashing bios with programmer..

Thanks again.... !
It's and smd chip, so I de soldered it from the motherboard and it's soldered on my pogrammer.. I can read/erase and program the chip... !
