So: your machine has 32MB of Flash storage that holds the entire system. On boot, it all gets loaded as a RAMDISK. Right? Question: how do you actually put a new system onto that Flash storage? What kind of Flash storage is it? (I suppose it's not a CF card or an USB flash drive that you would plug out, put an image on it, and plug in.) > Hard to believe, I know, but what people do with OpenBSD is sometimes > quite different from what you know from "usual systems". It certainly sounds interesting. Out of curiosity: what do these system do? Are their routers?

A dmesg from the actual machine would; really, it would.
