Alienware 17 r4 bios chip location?

[icetech]

Hope this is in the right spot, i'm not asking for bios files just some help figuring things out

So. i have an alienware 17 r4 in with motherboard la-d751p bap10.. Dell released bios for it that bricks it and thats what happened, bad enough that bios recovery doesn't work. Laptop worked perfect until this bios upgrade..

I ordered a programmer and am reading/watching videos on how to flash it, my main question is, has anyone here done one of these and if so do you know the location of the bios chip? (I haven't pulled the board out yet but am trying to get my ducks in a row beforehand..)

Second, i haven't done chip programming before but it looks simple enough except.. should i just be able to extract the rom out of the dell bios file with -writerom (or whatever the command is) and just flash it? or do i need to do something else special?

Thanks a ton guys.. i hate to give up on a $2k laptop over something this dumb..

Programmer showed up, tried the file above but no post, no beeping at least, but the power LED is showing unknown CPU..

They made this laptop with a kaby and skylake cpus.. think i need to find a different bios file.

SPI ROM for main BIOS is located near PCH.
