     Yes, and my point is that I'm able to boot both types of systems
using the "new" PC boot method and thus you can use both PC CD boot
methods in conjunction with Sun's boot method.

     This is a different problem.  However, from other posts, it
appears that it has been solved as well.  I don't know if all three
systems can be combined on one CD though.

     BTW, while on this subject, I'm wondering why hp700 can't use the
makefs -o bootimage=sysid:filename syntax that other systems use?
