There are some differences, at least in so far I remember from
reading both of the systems' the manuals, but highly likely none
to (the typical) 'end-user'.  I think one of the differences was
in the 'memory cell' design, but it's been years since I read
these manuals, so I don't know for sure.

I should have spoken for myself.  For me it was of zero use and
I never got that combination to work, now you remind me because
I think I did try this combination once (when I may have obtained
an AGP Radeon card, by accident likely, and I also remember
reading on Hoffman's site that it's a minefield, anything
involving AGP and as far as solid support by VMS goes).

I also saw no reason to have a 'dual-head' setup in combination
with DECwindows, since I mostly used the excellent CLI anyway.

I remember that if there was another graphics card present, the
on-board MP/iLO graphics adapter was disabled.  I was also not
aware that there were MP/iLO cards with anything other than the
Radeon 7000 for rx2600s, rx2620s or even the rx4640 (the only
IA-64 hardware I personally ever dealt with).
