The differences you see are basically just differences in features
offered by the various BIOSen. If you look through the archives (and I
posted once to linux-poweredge as well,) I have posted a couple lists of
every pxe-related token.

If you are trying to create a unified system, it is hard. You will have
to have some backup logic for the systems that dont support the tokens
you need.
