- 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.
