I did not belive him even after he explained what happened. Later on I got confirmation that this could indeed happen. He had an IBM and a hercules graphics card that he was poking registers at. Seems that you can poke some values in that card (possibly others) that cause it to put out I belive a much higher frequency signal to the monitor than the monitor can handle. A few seconds of that and he had smoke curlying out the top of the monitor and the monitor was dead. I would suspect that the new graphics modes and monitors get into these frequency ranges and if you have the wrong monitor attached the possibility of it going poof is fairly high. -- _ /// /_\ Scot L.
