I have "Hiren's BootCD" .. you can buy it
By the CD it's so easy to remove any password
there is a way but it's 50% working .. In the motherboard there are place like that "lll" and it's covered by a cover of 2 shows like that "Hl"
ok you have to turn the cover to be like that "lH" and turn it on .. it will not turning on
then replace it on his place .. ( this step reset the motherboard )
this method fine for the DOS password maybe it's working for the administrator
