fdmake

fdmake is a DOS utility that creates floppy disk images that can be mounted with DOSBox. It is written in assembly language and should work with any x86 processor, even the ancient 8086.

Build

fdmake requires Borland Turbo Assembler to be built. The build process was tested against version 5.0, but may work with lower versions as no version 5.0 specific directives were used.

Assuming the BIN folder of Turbo Assembler is in your PATH environment variable, run these two commands at the DOS command line prompt:

> tasm fdmake.asm
> tlink fdmake.obj /t

The /t switch instructs the linker to create a .COM executable.

Usage

If you run fdmake without arguments you get a detailed help screen:

Creates a floppy disk image.

FDMAKE filename [/T type] [/L label] [/U] [/F]

  filename  Image file to create.
  /T        Type of image: 360k, 720k, 1.2m, 1.44m (default), 2.88m.
  /L        Volume label (max 11 characters), ignored if /U is set.
  /U        Writes an unformatted image.
  /F        Overwrites the existing image file if it exists.

imgmake

This small utility implements a subset of the functionalities provided by the imgmake tool, which also allows creation of hard disk images. It is present in DOSBox-X as a builtin, or is available as a standalone port at the following repository:
