WHAT'S NEW?

[VERSION 2.80] - Corrected pointer problem responsible for the majority of QEMM
                 and other memory-related errors.  Now you can truely use
                 POLYCOPY and QEMM safely and reliably together.

                 IMPORTANT:  Don't forget to increase the number of available
                             XMS handles to 128 (see documentation).  If you
                             are using ans Extended Memory Manager (EMM) other
                             than HIMEM/EMM386 or QEMM, refer to the
                             documentation that came with it to see how to
                             increase XMS handles.

                 Increasing the number of XMS handles makes it possible for
                 POLYCOPY to copy entire 1.44MB diskettes entirely in RAM.
                 
[VERSION 2.70] - Read/Write elapsed time display.  After a complete disk read or
                 write the elapsed time for the process is displayed in the form
                 [XXm XXs], where 'm' is for minutes and 's' seconds.

               - TrashGuard<tm> RAM validation protection.  Some EMM drivers,
                 such as QEMM, can make dangerous modifications to DOS RAM
                 without warning if they are not configured properly for your
                 system.  A change to a single byte will not affect most
                 programs noticeably; however, when you're copying diskettes a
                 single byte error cannot be tolerated. Enter TrashGuard.

                 TrashGuard does exactly what it's name implies, it guards
                 against trashed data.  An advanced 32-bit CRC algorithm is used
                 to detect changes to diskette data while it is stored in RAM.

               - Verify option.  In verify mode POLYCOPY does in verify mode is
                 to read each track written to disk and compare every byte to
                 insure an absolutely accurate write.

               - No more erroneous "Drive not supported or is not a floppy
                 drive" errors.  If you get this error now chances are it is
                 legitimate.

               - Extended drive letters.  This version supports any floppy drive
                 letter -- including virtual drives.  Letters such as those
                 assigned by MicroSolutions' CompatiCard IV (i.e. E: F:).

               - DiskDUP (Copr. (C)1990 R. MacClean) image file compatibility.
                 This version allows you to restore from DiskDUP's image files
                 that are not compressed.

               - Tested with fast, single-pass copies on 600 rpm high-speed
                 floppy drives.

[VERSION 2.60] - Store to and restore from diskette image files.  These disk
                 images may be archived for modem transmission or simply stored
                 on you hard drive for diskette recreation without the need for
                 an original.

                 NOTE:  The image files POLYCOPY creates are completely
                        compatible with those used by the PC Magazine utility
                        pair 2FILE/2FLOPPY (C)1991 Ziff Comm. Co.

               - DOS 5.0 compatibility

               - Added "/u" parameter to the DOS FORMAT shell when DOS 5.0 is
                 detected.

               - Added "/x" parameter to disable XMS memory usage.  This is
                 primarily for testing and comparisons, but may also prove
                 useful if you have XMS problems and don't want to go to the
                 trouble of removing your HIMEM.SYS driver.

               - Removed disk status check when "/f" forced format parameter is
                 specified.  This eliminates the long pause associated with
                 cross-formatted diskettes, but only if "/f" is specified.

               - Fixed bug that occurred when insufficient XMS handles resulted
                 in a switch to DISK producing a corrupt target.  It is still
                 recommended that you install:

                        "DEVICE=C:\DOS\HIMEM /NUMHANDLES=128"

                 for the best possible performance (HANDLES=128 for QEMM).

               - Added "/r" parameter so POLYCOPY can now generate its own
                 registration form.  Use the following syntax to print a
                 POLYCOPY registration form:

                        C>polycopy /r > prn

[VERSION 2.22] - Earlier versions skipped side one of the last track on high
                 density diskettes.  This has been corrected.

[VERSION 2.21] - Fixed bug that occurred when copying multiple, different disks.
                 The first disk always copied fine, but the program didn't
                 reliably free up XMS and RAM prior to starting another disk.

[VERSION 2.20] - XMS memory support!

[VERSION 2.12] - Gives "WARNING!" rather than error when user attempts to make
                 the default drive equal to either the SOURCE or TARGET drive.

[VERSION 2.11] - Corrects formatting problem, "bad parameter," for DOS versions
                 less than 4.0.

[VERSION 2.10] - Multiple disk drives supported.
