Re: Via KT400 and AGP 8x Support

Hi i will look into that with the bridges, i hope that Hercules is so that
they give me the spec´s (Plan of the Card) with the Jupers/Bridges for AGP
2.0.

The minus on Performace is not great, in my eyes.

It´s very SAD that Ati and Nvidia will not give the Specs or an Sourcecode
of the Drivers :/.

Regards
