RaWrite is an MS-DOS utility similar to dd(1) which allows writing a disk image file to a diskette.
In this example, once you pressed enter, you'd get the file D:\images\scsinet.img written to the floppy in A:. You will then get a message indicating whether your disk was created successfully.
Those who prefer GUIs may want to use Winrawrite instead.
