No, sorry. I tried to fool vmware several times to make it think the iso was a cd, and see if it\'d boot, but no go. And there\'s programs that\'ll mount an iso like it was a regular cd. But they don\'t load until after you boot (and no they won\'t work with vmware, tried that too).
So basically, ya just gotta get a pack of CDRWs and do all your testing on those.
