Hello,


Thank you for your previous reply.


I have already reprogrammed the full BIOS on the DA0NJHMBAH0 REV_H motherboard after replacing the SRKMA (Southbridge/PCH).
The programming was successful (erase → write → verify OK), but the issue remains unchanged.


Symptoms:

• After power on, the board draws about 0.6 A, then rises to 1 A, stays for a few seconds, drops to 0.15 A, then repeats the cycle (0.6 A → 1 A → 0.15 A → …).
• All voltage rails are present and stable.
• The new SRKMA no longer overheats.
• No display output.

Since the problem persists after a clean BIOS reflash, I suspect the BIOS content may need correction (e.g. ME region clean, DMI/MAC/NVRAM data alignment, EC/Bios synchronization, or board ID fix).


Could you please:

1. Repair or rebuild the BIOS so it is fully compatible with the replaced SRKMA and this exact board.
2. Provide a correct EC firmware for MX25V8006EZNI (1.8 V).
3. Let me know if I should send you my saved EC dump to assist with the repair.

Once I receive the corrected files, I will reflash both the main BIOS and EC and retest the board.


Thank you for your support — I’m ready to proceed as soon as you provide the necessary files or instructions.
