mkhfimage - Utility to add an image validation header.
mkhfimage -i <filename> -e <filename> <input file> <output file>
mkhfimage is a utility used to add an image validation header onto an image or other file in an ISOS system. The header can then be checked as part of the boot or update process to ensure that the file is appropriate for the hardware it is running on.
It is usually run from the mkproduct.pst file as part of the build process.
mkhfimage -i image -e image image.comp image.val
This will add an image validation header into image.comp, using the file image for the both exec header and image information it generates the file image.val.
