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