The +ISO9660 specification allows for a 512 byte region which is for +application use. We use it to store a checksum of the ISO image. Of +couse putting the checksum into this region will change the checksum +of the final ISO image, so when we verify the checksum later we have +to fill in this 512 region with the original contents before the +implantation. It is set to all ASCII 32 decimal spaces. + +If you have a set of ISO images you can implant the checksum data with +this command: + + implantmd5iso <isoname> + +NOTE: You cannot re-implant an ISO once its been implanted. + +To check a ISO image you can use this command line: + + checkisomd5 <isoname> + +The tools are in the anaconda-runtime package, currently in the +/usr/lib/anaconda-runtime/ directory. + |
