Chiliflash. Basically it's a serial app that sends a ZCX and reads back status. I've never been able to talk to these things with a serial program like PUTTY, never know the baud rate or stop bits. Oh well, someday.

I haven't tried to download the code yet, if the ROMs are protected that won't work. I don't think the Atmel will brick if you just try to read, I'll give it a shot tomorrow after running for a day with no problems.

Do they make a high pitch whine? I don't think that is a problem between BFG and queue. Still, you're getting more hashing than you bought, so be happy. Let's think this through for a bit, if you can get some sort of details on the message it might help. Maybe the two messages are related. Thinking.

Who else is getting those messages, and where are they?
