Hi Weblacky,

thanks for that, it make good sense as the Fuel system ID corresponds to the Ethernet MAC address for ef0 interface (and the IO9 board on the O350 also has Ethernet port, though systems ID is over-written by the one that is programmed via L1 / L2). From Fuel:

So location of Bedrock PROM is still TBD...

BTW, looking forward to seeing positive result with your Fuel repair, which looks like it is going really well.
I see you have moved Fuel from "want" to "have" in your signature ;-)
