I would like to create/install a method of logging in which would give a user-defined number of attempts to login correctly, or cause the hard disk, and any other external media, to be wiped(preferably by writing all 1's or 0's or random 1's and 0's).
It would need to be able to wipe the disk(s) from the very beginning(boot sector) to the very end.
I'm not sure if this post is in the correct board, but I know admin will move it for me if it isn't.
This login would have to happen right after the BiOS, perhaps even be part
of the BiOS.
Or, should I try to do this through GrUB?
If anybody has any experience with this, please help.
