go to start>run and type cmd
a small black window should open, in it type "debug" without quotation marks
then type:
-o 70 10
-o 71 20
-q
exit
now restart your comp and go into bios, the password should not be there.
try this also in cmd type debug and then
-o 70 2e
-o 71 ff
-q
this one works for other bios's
