Anti-aliasing with GeForce Line

I have tried anti-aliasing with the jittering method using the accumulation buffer as demonstrated in the Red Book. However, my GeForce-2 MX apparently has no hardware support for the AB, so my performance drops from around 60 fps to 1. I know nVidia has some method for "full-screen anti-aliasing," (as described on my card''s box) so I''m trying to figure this out. Is it an extension? If so, where is it documented? How do the major game designers do anti-aliasing, if the accumulation buffer is not even implemented in hardware on some cards? Thanks much for any help.
