Creating a CD from an ISO image An ISO image is a file that can be used to create a CD in ISO-9660 format, which is a CD file structure that can be read by Windows, Mac, and Linux/Unix systems. When you download the ISO image use ftp and make sure you get it in binary format. The default format for many Windows ftp programs is ASCII, not binary. Netscape downloads default to ASCII, which won't work. ** NOTE ** Before you burn the CD image make sure the cksum and md5sum values match those on the FTP site. For linux/unix systems use: $ md5sum cd_image.iso and $ cksum cd_image.iso Windows users you will need to download and install the GNU text processing utilities located at: http://atnetsend.ne.mediaone.net/~paquette/WinProgramming.html Once installed follow the directions as listed above. A difference in the values may be as a result of an incomplete download. Do not attempt to burn the CD image unless the values match! After you have downloaded the image, you have to "burn" it onto the CD disk. You cannot copy it onto a disk using Direct CD or other software that makes the CD disk work like a hard disk that you can just copy files onto. The most popular Windows software for doing this is Easy CD Creator, though there are other products that work as well. Check the software that came with your CD drive. On Linux systems, you can use CD Record to create the disk. No matter how you create the CD, make sure you have inserted a blank disk before you start.
