          3.  dtSearch for Windows
          ========================

              If you have both dtSearch for Windows and dtSearch for DOS,
          you may wish to install both programs in the same directory so
          that the two programs will recognize the same indexes.

          4.  Hardware Requirements
          =========================

               dtSearch for DOS requires DOS version 3.3 or later, a 286 or
          higher processor, and at least 2 megabytes of memory.

          5.  DOS Extender
          ================

              dtSearch for DOS uses a DOS extender, which allows it to use
          memory above the lower 640k.  On systems with 2Mb of memory or
          more, this eliminates problems running dtSearch in low-memory
          environments.

               The Phar Lap DOS extender used in dtSearch for DOS is
          compatible with nearly all DOS environments in use today.  Most
          users should be able to simply run dtSearch for DOS without
          altering their system configuration at all.  If you experience
          problems, check the following:

               2 Mb systems
                    If your system has exactly 2 Mb of memory and you are
                    using a disk-caching program such as SMARTDRV or
                    PC-CACHE, the cache may not leave enough memory for
                    dtSearch to run.  Try reducing the cache size to 256k.

               EMM386.EXE
                    The DOS extender is incompatible with one specific
                    EMM386 setup: the version of EMM386 included with DOS
                    5.0 or Windows 3.1, when used with the NOEMS parameter. 
                    If you encounter this problem, edit your CONFIG.SYS
                    file and look for a line like the following:

                         DEVICE=C:\DOS\EMM386.EXE NOEMS

                    Change NOEMS to FRAME=NONE, like this:

                         DEVICE=C:\DOS\EMM386.EXE FRAME=NONE

                    This problem has not appeared in more recent versions
                    of EMM386.EXE to date.

               QEMM.SYS
                         Some versions of QEMM have the same problem as the
                         DOS 5 version of EMM386: "NOEMS" does not work
                         with dtSearch, so just change "NOEMS" in your
                         CONFIG.SYS to "FRAME=NONE."
