    So I have an ISO that Intel made for it's X-25M firmware update which boots freedos and I want to add HDDERASE to it. Just maybe it will work from that instead of UBCD but it's worth a try.

    How is that possible?

    are you asking how to write to the ISO image? well Mac OS X can mount ISO disk images natively so just double click on it, write to it and then eject.

    Are you sure OSX can mount an iso with read/write permissions ?

    I have an ISO image that Intel put out and it boots on my machine.

    I simply wanted to add a file HDDERASE to that image and burn the image.

    I'm not sure how to create the image

    I opened the ISO image and built a DMG from it and used the following
    command

    diutil makehybrid -iso -joliet -o HDDERASE.iso HDDERASE.dmg

    but the CD won't boot so something's wrong with the ISO.

    It doesn't need to the general idea is to build a DMG from the mounted ISO contents and convert the DMG to ISO but it's not working for me.

    yes

    in Disk Utility make a disk image from a folder containing your files from the File menu and make the image format "CD/DVD master". then rename it from .cdr to .iso and then burn the .iso with Disk Utility.
