yes all the SB development is iterative from SB400. all new SB comes with new feature and put on old one. but there is a some differences, because of this , It needs some development for SB700 and sometimes SB600 kext or patch does not work with SB700. I tried leo4all it worked but it didnt serve the speed.

and I want to say that ideneb didnt have SB400/500/600 support in fixes or patches.

am I wrong? which release did you get? can you pm me?

I think , our last kext is better than other because it has own performance rather than some modification because some of the kext modifies the MACOSX Server SATA option to get working with ATI IXP.

someone can share knowledge about IGP HD3200
