"this can be interpreted in more than one way." One flavor can be seen in the A20 gate http://en.wikipedia.org/wiki/A20_line http://en.wikipedia.org/wiki/A20_line 30 years after it was inserted into the architecture to work around some software issues/bugs, bootloaders still have to fool around with it every time a x86 machine is booted. Lovely.
