The chip comes from Bad_Ad84 so I trust it's correctly burned. I've now removed the new bios and checked all traces which are fine. One thing Bad_ad suggested was to check the traces under the three dots of glue, but they are unfortunately fine as well. I have absolutely no idea where to go next. Edit: Solved! Found a sneaky via with a severed connection to a pad. A big thank you to bad_ad84 that took time to offer advice in several pm:s! As others have stated it's not a very good idea to clip the legs on the original bios. Did another one with a proper smd station and had no damage to that board.
