ThunderZ,
I understand your point, but I am a safety man.
When I had that problem, than I don't take the risk.
Or I say to myself and sometimes have I that period: Know you what, I do it and see what will be happen, have I luck, than hurray, is it else, pity, than have I bad luck and buy a new one, in that case have I usually too much money.
But I do know that, that stuff is expansive and when the computer works correct, than I let it for what it is, I am not happy when my machine works correct and I get an update for the Bios and update the Bios and after this, I have a problem and I see that it is not possible for clear the cmos.
My thinking in this all is than too: Why should you take the risk that what I did tell can be true and you get troubles after this.
Sorry guys that I telling this, but we are here on a forum for helping together and giving advice is also help.
