Unfortunately, I've seen this problem all too often. I've even had the
fun experience of burning a disk and having it boot on one machine, but
not another -- even when both were using the same model of CD-ROM drive.

There's not a problem with the file per se, but I've noted in the past
there's something about how it's formatted that makes it damn touchy
regarding the combination of burner, burning software, and reading

You would think the Blades would have a more forgiving CD-ROM drive, but
the last one I worked on made me jump through some serious hoops to get
the Solaris 9 images burned in a format it would take. My problem ended
up being the media -- I had to find some of the older CD-R media that
was only 650MB and only worked in 4x burners.
