[Request] bc-250 bios unlock

Hi i would like to request a bios unlock for a bc-250 mining system, it has ami bios that i dumped that has 16.67 mb in size, the bios cant be found anywhere on the internet, the bios itself has very few option and no options for or even information about cpu, gpu, if someone can unlock some of the advanced features and maybe overclock features i would be thankful, also gpu memory frequency change is locked and i dont know if its bios or elsewhere. Thank you in advance. Motherboard maker is Asrock, it was downloaded from bios chip using Afuefix64.
