bximage - Interactive Disk Image Creation, Conversion, Resize and Redolog Commit Tool for Bochs


bximage [options] [filename1] [filename2]


Bximage is an easy to use console based tool for creating, converting and resizing disk images, particularly for use with Bochs. It also supports committing redolog files to their base images. It is completely interactive if no command line arguments are used. It can be switched to a non-interactive mode if all required parameters are given in the command line.


When you run bximage without one of the following options, it will appear in interactive mode and ask for all required parameters to manipulate an image.

Operation to perform (create, convert, resize, commit, info)
Create: floppy image with size code (e.g. 360k, 720k, 1.44M)
Create/resize: hard disk image with size in megabytes (M) or gigabytes (G)
Create/convert: hard disk image mode - see the bochsrc sample for supported options.
Convert/resize: create a backup of the source image. Commit: create backups of base image and redolog file.
Quiet mode (don't prompt for user input). Without this option bximage uses the command line parameters as defaults for the interactive mode. If this option is given and one of the required parameters is missing, bximage will fall back to interactive mode.
Print a summary of the command line options for bximage and exit.

The filename1 parameter specifies the name of the new image (create), the source image (convert/resize) or the base image (commit).

The filename2 parameter specifies the name of the destination image (convert/resize) or the redolog (journal) file (commit).
