  This function is the primary interface to the internal\r
  forms-based browser. By calling this routine, one is directing\r
  the browser to use a variety of passed-in information or\r
  primarily use the HII database as the source of information.\r
\r
  @param This   A pointer to the EFI_FORM_BROWSER_PROTOCOL\r
                instance.\r
\r
  @param Handle   A pointer to an array of HII handles to\r
                  display. This value should correspond to the\r
                  value of the HII form package that is required\r
                  to be displayed.\r
\r
  @param HandleCount  The number of handles in the array\r
                      specified by Handle.\r
\r
  @param SingleUse  If FALSE, the browser operates as a standard\r
                    forms processor and exits only when\r
                    explicitly requested by the user. If TRUE,\r

                            adjusted to comply.\r

  @param ResetRequired  This BOOLEAN value will tell the caller\r
                        if a reset is required based on the data\r
                        that might have been changed. The\r
