Hello everyone!
I would like your help modifying a BIOS dump. I backed up the original chip using an EEPROM programmer.
The Problem: I'm having a problem with the power supply in this Mini PC. When I turn it on, the BIOS displays the following message in red:
"Incompatible power adapter wattage! If the power is insufficient for the system load, limitations may occur. Please refer to the product manual."
Immediately afterwards, the device powers down (shuts down by itself).
Because of this, I can't load the operating system or even navigate the BIOS menus to try to disable this warning.
I would like to know if there is any hidden option in this BIOS that allows me to disable this power supply check, or if this is a physical hardware limitation (power supply ID circuit).
Does anyone know how to disable this lock in the binary file?
What I've already tested:
Searching online, I discovered that the ASRock Jupiter Q370 mini PC uses a motherboard practically identical to this one from Positivo (POS-RIQ370EB, which is actually manufactured by ASRock).
I tested it by flashing the BIOS of this ASRock Jupiter onto the Positivo motherboard. The mini PC turned on perfectly, didn't display any power supply errors, and started the system normally.
However, I noticed that one of the USB Type-C ports stopped working (probably due to some difference in the USB/ACPI port mapping between the two firmwares).
If I revert to the original Positivo BIOS, everything works, but only if I use a specific original power supply.
Since the hardware works perfectly with the ASRock BIOS, I believe the power supply lock is purely a software lock placed by Positivo. Could someone help me edit the original dump to remove this check?
