Dear Badcaps companions,


We got an Acer Predator Helios for repair that's missing the VBIOS chip (UV2). I already figured out that the chips is a Winbond W25Q16JWSSIQ so we're looking for a 2MB dump that's no where to be found.

Thanks in advance,

Upon inspecting the motherboard, I noticed that the BIOS is composed of two chips: one 8-pin 16MB chip and one 16-pin 32MB chip.

I have attached the BIOS. Could someone help me clean it please......
