Re: samsung NP300E5C- bios problem

The bios chip used on this platform is 8MB . So you can try using 8mb,3v bios chip. There are several variant of bios. You can try with these two bioses attached.

Measure voltage on all grey coils and post here. I doubt you have missing gfxcore

Re: samsung NP300E5C- bios problem

before unsoldering the bios chip that was mounted on the main, the display turned on, but the bios did not show the HD, so I thought of an error in the bios, so I'm looking for the right bin file

Try this bios,its the right one for your motherboard.If it doesn`t work i suspect the PCH needs replacing.

Re: samsung NP300E5C- bios problem

This bios do not work, maybe the problem it's the chip? The first it's MX25L64O8E, I ave used W25Q64FVSIG , 8Mbyte, 64Mbit, it's compatible?
