hi i have a concern, i have a unit here unit model predator helios 300 with motherboard board model gh51p la-k862p, the story of this unit if from authorized service center and they repair the bios chip, so now i am the 2nd engineer and my concern here this unit have two bios chip but they have a deferment voltage input, the 1.8v is near in graphics ic and the other one 3.3V near at the PCH, the previous service center they program the 1.8v bios only so i doubt if they apply the 3.3v but this is fine i can replace new one bios but my main problem here is i dont have the original bin file og 1.8v bios chip because now i cannot read or back the old 1.8v because is damage, the error i encounter is verification error even i add new ID on my rt809f still same error, here what i found, i locate the 1.8v bios chip on board view and says this 1.8v bios belong graphics chip and i thought this is a graphic chip driver and don'tbios.PNG know also what i should to use bin file of 1.8v bios
