I snipped the rest, but your point ignores that they still have to scan my
hard drive for what they are looking for. So TEMPEST on top of the other
measures just makes things slower. Also the vast variety of computers and
clock speeds on the market today would make a 30 byte (10-20 clock cycles
... )BIOS patch virtually undetectable. Again...UNLESS they want YOU in
particular. 

I would be more concerned about a Unix-like OS on their disk-following THEM
to bypass my BIOS to read the HD. Of course, perhaps another way around
this may be to carry a couple copies of an NDA and an Acceptance of
Liability for Damages Caused contract. Tell the stooge at the counter that
your machine contains highly valuable commercial information and that if
it's damaged in any way, shape or form he/she will be held personally
liable. Offer the two documents for his/her signature as you explain that
since the procedure they intend to use is so fool proof (the stooge is sure
to quote the party line...) this would only strengthen your case that
damage or discloser to/of contents must be a direct result of negligence or
criminal intent on the part of the stooge.

"If you can't dazzle 'em with brilliance, baffle 'em with bullshit." It
works for Clinton!
