HELP ME PLEASE PART II!!!!!

[PEEKB@GAR.UNION.EDU ("Brian Peek, w/ A. Rauch ", CABBS)]

I wrote a message previously to which no one replied, so here is a follow-up
with a little more information.  I have the assembly source code (I don't know
assembly AT ALL!!) and it tells what the "secret" key is to unlock the hard
drive.  If anyone knows assembly and can decipher what the secret key is,
please tell me!!!  I can't get into my hard drive!

Here's the source code:

*======================================================
* PassKey protection program

* Upon booting this program clears the keystrobe and checks
* to see if the 'secret' key has been pressed.  We allow that
* it may be cleared by another program.

* Written by Lane Roath to keep 'people' off his machine!
