    This may be true(infact it is true) but is a sign that your administrator
    forgot or did not know about F8.  This was the case at a school i know
    that just setup FoolProof, forgot F8, and diskette booting, but that was
    negligence.
    So here is another problem in foolproof
    
    Bug/flaw:
    
    A bug that for all intensive purposes is a bug.  If you can execute 'echo'
    with 4 command line arguments  you can disable (esentially delete)
    foolproof.
    
    Implication:
    
    Disable _protection_ (if you can call it that) from FoolProof.
    
    Exploit:
    echo Hi > c:\fool95\fooltsr.exe
    Do this with every file in the foolproof dir (The install directory may
    vary).
    
    Fix:
    
    Run a UN*X os instead of a Microsft product?
    Seriously though, I have not looked into side effects(or if even possible)
    to disable 'echo', so making all files in the foolproof dir (and elsewere
    through out the computer, have not looked for them all) read only so you
    _cant_ write to them, but also disable attrib changes.
