- PREAMBLE:
-
- Have you ever used the DOS "diskcopy" command with a 3 1/2"
- floppy disk or a 5 1/4" high density floppy? You are forced
- to swap disks several times to get the job done. This is
- because DOS is limited to 640K of RAM for program use. A
- 360K floppy disk can be read in one pass because it fits
- within the 640K limit. But other disk sizes cannot be read
- in one pass due to their larger size. So you are forced to
- play musical disks until all the data is transferred. I
- stopped using the diskcopy command because it was such a
- hassle.
-
- I decided to write EMSCOPY.EXE to do what DOS does not -- read
- any size floppy disk in ONE pass and copy it to a blank floppy.
-
-
- DESCRIPTION:
-
- EMSCOPY.EXE is a replacement of the DOS "diskcopy" command. A
- source disk is read into EMS memory, which is then transferred
- to a blank disk. Any size floppy disk will be copied in only
- one pass. If there is no EMS memory, or not enough, the hard
- drive will be used for the transfer. The result will be an
- EXACT duplicate of the original.
-
-
- LEGAL STUFF:
-
- This program is free-ware, part of the Public Domain. You may
- copy this program freely and use it free of charge. Under NO
- circumstances shall this program be sold or included as a part
- of any sale.
-
- This program is distributed as-is, with NO warranty of any kind.
- Use at your own risk. I have tested this program on various 80286,
- 80386, and 80486 based computers using MSDOS 3.01, 3.3, and 4.01
- with no problems.
-
-
- REQUIREMENTS:
-
- ** An IBM AT or compatible computer.
-
- ** MSDOS 3.01 or greater.
-
- ** 1.44 megabytes of free EMS memory OR
- 1.44 megabytes of free hard disk space.
-
- ** An EGA or VGA monitor. I don't know if
- this program will work with monochrome.
-
-
- USE:
-
- This program is very easy to use. Just type EMSCOPY, and follow
- the directions. You will be asked to insert the source disk and
- enter the drive letter. Only Drive A or B are supported. The
- disk will then be read, followed by an audible tone to signal
- completion. Next, insert the target disk and press a key. The
- disk will be written to make an exact duplicate of the original.
-
- Important: The target disk must be a BLANK FORMATTED disk of the
- same size as the original. If the target disk is not
- blank, has bad sectors, or is a different size, an
- error message will result.
-
- If DOS gives the message "Abort, Retry, Ignore" or "Abort, Retry,
- Fail", DO NOT choose Abort. Nothing terrible will happen if you
- do choose Abort, but one of two things may result:
-
- 1. Some EMS memory may be locked-out and unavailable until you
- re-boot. This should not be a problem. It will not affect
- the operation of your computer or harm any program.
-
- 2. If the hard drive was being used for the transfer, a file
- called "disk.dat" may be left behind. You can erase it if
- you want to. It will be deleted the next time you run EMSCOPY.
-
- It's best if you stick to "Retry" or "Ignore/Fail".
-
-
- TECHNICAL NOTES:
-
- EMSCOPY was written with Borland's Turbo C 2.0. For graphics and EMS
- access, I used Mike Smedley's very useful CXL Extended Function Library.
-
- I would be very interested in hearing your comments, suggestions, etc.
