FDI2IMA v1.00

Converts FDI-files from TDCVT v0.11 to IMA-files for Winimage.


----- Description ------

You can use this program (in conjunction with TDCVT v0.11) to convert a
Teledisk TD0 file to the format of Winimage (IMA). With Winimage it is
possible to comfortable extract files from the image, while with Teledisk
you can restore the TD0 image only to a disk. This is sometimes even
impossible if you have an image of a 5 1/4 inch disk and don't have a
fitting disk drive.

Make sure that you use at least version 0.11 of TDCVT, because previous
versions had a bug (loosing last track of TD0 file). I tested TDCVT and
FDI2IMA only with images of MS-DOS-disks, so I can not guarantee that
other formats will work.


----- How to use ------

Unpack the archive TDCVT011.RAR to any directory and add the files
FDI2IMA.EXE and TD2IMA.BAT into it. Then start TD2IMA.BAT with the name
of the TD0 file without extension. Example:

TD2IMA FILE

Now you have hopefully an IMA image, which you can load into winimage.


----- Use without a BAT file ------

If you have TD0 images from Teledisk, you must first convert them with
TDCVT.EXE v0.11 (and maybe TDUNP.COM) into FDI. Example:

TDCVT -f FILE.TD0

If TDCVT fails with the error "Packed file, please use TDUNP first", you
must use TDUNP, but make sure, that TDCHECK.EXE is in the current directory.
Now you have a ZD0 file, which you can convert with TDCVT to FDI.

Finally you start FDI2IMA and convert the FDI file into IMA:

FDI2IMA FILE.FDI [Size_of_Disk]

"Size_of_Disk" is the size of the disk in kilobyte (e.g. 360). It is
optional, so if you don't enter it, FDI2IMA will try to find out himself.

----- Tested with ------

Teledisk 2.16 (2.12 doesn't work on my computer)
TDCVT v0.11
Winimage 5.00.5000
MS-DOS 7.0
Windows 95b
360K,720K,1.44M Diskimages


----- Known Issues -----

* Teledisk 2.16 seems to have trouble in DOS Boxes
* Winimage hangs if the IMA file is currupt
* TDCVT and FDI2IMA are in a experimentical status
* It is possible, that FDI2IMA cannot find the right sector size, if
  you feed it with FDI images not created by TDCVT. Just hand over
  Size_of_Disk to work around this problem.


----- Technical -----

You just have to cut the header of the FDI file, fill the file up with
some 0xF6 bytes and you have a IMA file, which you can load in Winimage.
The IMA file is a 1:1-dump of the data on a disk.
