im trying to connect 19 gpu motherboard but it only recognized 14 with 4 errors (red squares)

I guess you’re try it on ASUS B250 Mining Expert. On MB manual said that configuration with 19 GPU need mining GPUs (like P106-100 or P104-100). On other motherboards need carefully read similiar section.
Hive OS itself should be Ok with up to 32 GPUs.
