Hardware-generated Exceptions
All INT_NUM between 0x0 and 0x1F, inclusive, are reserved for exceptions; INT_NUM bigger than 0x1F are used for interrupt routines. (Note that the IBM PC did not always obey this rule, for instance using interrupt 5 to indicate the Print Screen key was pressed.)

Famous quotes containing the word exceptions:
“... people were so ridiculous with their illusions, carrying their fools’ caps unawares, thinking their own lies opaque while everybody else’s were transparent, making themselves exceptions to everything, as if when all the world looked yellow under a lamp they alone were rosy.”
—George Eliot [Mary Ann (or Marian)
