It is sometimes necessary to create a diskette from an image file (for example, you might need to use updated diskette images obtained from the Red Hat Linux Errata).
As the name implies, an image file is a file that contains an exact copy (or image) of a diskette's contents. Since a diskette contains filesystem information in addition to the data contained in files, the image file is not usable until it has been written to a diskette.
To start, you'll need a blank, formatted, high-density (1.44 MB), 3.5-inch diskette. You'll need access to a computer with a 3.5-inch diskette drive, and capable of running a DOS program, or the dd utility program found on most Linux-like operating systems.
The image files are found in the following directories on your Red Hat Linux CD:
On the Red Hat Linux/SPARC CD, this directory contains the boot image, and an image for network booting.
Once you've selected the proper image, it's time to transfer the image file onto a diskette. As mentioned previously, this can be done on a DOS-capable system, or on a system running a Linux-like operating system.
