There is a whitepaper available for download that provides information on how to set up a bootable USB drive to deploy an image (or images) to target systems, using Image for DOS Version 2 as the imaging tool.
The zipped archive linked to below (usbsetupv2.zip) includes a FreeDOS-based boot disk that can be created using MakeDisk as a bootable diskette, CD/DVD, or USB Flash Drive. The boot disk can then be used, along with the whitepaper, to set up a bootable USB drive for deployment, using either FreeDOS or TBOS as the operating system.
The archive also includes prepared images of TBOS and FreeDOS partitions that can be restored directly to the USB drive. The restored partitions will then need only to have Image for DOS added to them, along with the image(s) to deploy.

Note: There is a previous version of this whitepaper that is specific to IFD Version 1. Please see the KB article linked to below if you need that version.
