  14 <H1>6.1  Why Protection?</H1>
  15 The purpose of the protection features of the 80386 is to help detect and
  16 identify bugs. The 80386 supports sophisticated applications that may
  17 consist of hundreds or thousands of program modules. In such applications,
  18 the question is how bugs can be found and eliminated as quickly as possible
  19 and how their damage can be tightly confined. To help debug applications
  20 faster and make them more robust in production, the 80386 contains
  21 mechanisms to verify memory accesses and instruction execution for
  22 conformance to protection criteria. These mechanisms may be used or ignored,
  23 according to system design objectives.
