Removed the bios chip pad and traces from the motherboard, likely the ground. Need some guidance!
Hello, I’ve just updated the Asrock H110 PRO BTC+ BIOS from version 1.10 to 1.60, but the system froze during the process (this has never happened before). The board won’t start up now. I’ve ordered a replacement chip, but when I removed it, I accidentally pulled the solder pad and trace along with it—probably because I lifted the chip before fully heating the connection. I suspect the damaged part is the ground pin, and I think I can follow its route to the tiny chip located in the lower right corner (refer to the photo). Do you have any advice on how to fix this? Should I connect a bridge from the bottom-right pin to the small chip? Based on other boards of the same model, the trace goes past this chip to the Clear BIOS area. Would it help to link the bios pin to that section? I’m really hoping for a solution and would appreciate any guidance you can provide. I’ve attached pictures of both the faulty and working boards so we can map the connection path. Thank you in advance, Tom.
I don’t know the exact function of that connector, but you can test it with a multimeter. If you find something, adding a little solder shouldn’t be too difficult. Do you have a method for flashing the BIOS chip from outside? The new chip is blank, so you’ll need an external tool to program it.
From what I see online, the chip features prongs that go into the PCB and are soldered from the back. You might want to apply some flux and wick to remove old solder, and you should be fine if everything checks out. If the chip lacks these prongs, add a small amount of solder to form a solid connection point. Use a multimeter to verify power flow and refer to the schematics to understand which pins correspond to specific voltages. It’s likely the traces are inside the PCB rather than on its surface.
The pin is connected to ground. Because the solder pad was removed from the board, you might connect that pin to a nearby ground and hope for success. Best of luck.
