I feel like I must be missing something obvious here... I'm using two pins (18,19) as output to drive relays. During boot I need them to be either high or low, but right now they seem to switch about mid-boot starting low and ending high. Is there a way to permanently set their state on startup?

Thanks, luz! I think I understand the situation much better after reading your response and finding the annotated pinout online.
