verify parameters with gascom software

I have an older honeywell mcu board I would like to know if someone out there could verify or set all parameters back to default? I have the boiler manual that lists all the parameters. It's giving me an E33 error "not listed" in manual. But I believe I may have accidentally changed one as I was stepping thru the parameters.
Thanks,Joe

PS. I would ship the board to you, it's from a Dunkirk Q95m-200 it has been very reliable up to this point. I had an indirect hot water heater (with electronic aquastat) fail and then had this problem after replacing the aquastat with a simple type(non-powered)type. no worries its all working now with a new mcu but was hoping to get this one working to have a spare
