@The_Editor >If its going to have anything to do with Amiga ... You can forget nVidia.
Indeed. Forefront tried cntacting Nvidia about us writing AmigaOS drivers for their chips. We wanted to NDA, no open-source, we'd do all the work and spend all the money, etc. but they didn't even have the courtesy to reply with a polite "Thank you but no", they simply completely ignored us.
Big companies like this will be hard to even talk to let alone work with or buy parts from. Consider the post's we've seen on these web sites claiming that Eyetech used the VIA southbridge for the AmigaOne as Via was the only vendor of such chips willing to sell parts in such miniscule numbers. And even then they won't provide adequate documention for the DMA issues to be resolved easily, those involved must resort to reverse-engineering PC BIOS code to figure out what needs done for AmigaOne.
Remember, the Amiga market is infinitesimal at this point. You may think that buying some hundreds units of each component for an production run is a respectable number, but the vendors consider this to be pretty much equivalent to zero units. It's going to be difficult to get their attention.
Note that somebody mentioned AGP4X vs AGP8X, thus the use of external examples. Anyway, IF Amiga is going mainstream then it has encounter mainstream issues.
Obtaining IBM?s G5 NB(e.g. CPC925) documents would be the ideal solution...
