I compared the original iso from Intel with the one generated by me and I really can't see any differences. My generated one is 9MB, and 8 MB of metadata seems a lot to me, or isn't it?. Don't know how Intel makes his iso's. Regards, Marco -- >From the moment I picked your book up until I put it down I was convulsed with laughter.
