Don't you know the reset cmos jumper usualy found on embeded products ?
If some bad person have access to it, I believe he'll format its disk, or even simpler to do directly on site : destroy it. There is NO sure local security in electronics.
By OWNING it you're able to give its serial, fax the bill, etc.
And what could I think when a robot-like person stupidely repeat me four times this same things, ignoring I am the legal owner of the product, needing an immediate solution instead of loosing time, nerves & money ?...Aver sucks, a lot.
