I don't know how hard this would be, but how about running a seperate memory check, and while those numbers are flashing on the screen, do the wait for imput?
So hide the keyscan in the memory counter code. Would work externaly, would probably not show up on TEMPEST. Since both the keyscan and the memory scan are repetitive TEMPEST might have a problem telling them apart. Provided you could get the keyscan in the same footprint as the mem check the BIOS would not show up as anomolous in size. As long as they're not running around doing checksums you'd be ok (I suspect). ____________________________________________________________________ The seeker is a finder.
