Thank you very much! I will try the file you sent and get back to you as soon as possible....

Hello everyone,

I'm looking for a full BIOS dump (.bin) for the ASRock H310M-HDV Rev 1.02 motherboard. The BIOS chip is a MX25L12873F (128Mb / 16MB).

I’ve already tried flashing the official BIOS from ASRock (version 1.40 and 3.30), but those are Instant Flash versions and don’t include the full SPI image (e.g. Intel ME Region, Descriptor, etc.). After flashing, the board powers on only when I short PS-ON to ground, and it fails to generate Vcore and 2.5V. Other rails like 1.05V and RAM voltage are present.

I suspect the original Intel ME and descriptor...
