  4.  |  This program demonstrates the BIOS interrupt timing functionality of    |
  5.  |  TCHRT V3.  The user may select from several BIOS interrupts to          |
  6.  |  "exercise", and appropriate activity is generated.  A BIOS interrupt    |
  7.  |  timer summary is then produced.  MSDOS interrupt 21h is timed in all    |
  8.  |  cases, which will show the user the relationship between operating      |
  9.  |  system and hardware activity.                                           |
