It's clear you don't know what you're talking about. A BSOD is not created when you reset your machine.
I believe he was making an analogy. A "hidden BSOD" is like you hit a hard reset button. There is a setting under XP that can be set so that instead of displaying a BSOD, when a catastrophic fault occurs, the computer just reboots. It's not like many people actually write down the codes the BSOD displays.
I can see this being of value to many people, who aren't particularly interested in the output of the dump a BSOD generates. For myself, when I have a kernel panic, I'd rather know about it. Since I haven't had one in ages, (since I don't do MS-Windows) I guess it's a fairly moot point.
His analogy is flawed though as there is no dump file. A hidden BSOD would still create a dump file.
Actually we can test his theory. Configure your XP machine not to reboot on crash. And then pull the plug.
Next check for the dump file.
