]Hi, ] ]I just want to tell "me too", so question is we go to direction of claiming less ]ram_resource as intel do or others.
So far there has been no comments about non-AMD UMA systems. This is one of several items that need to be resolved before the trunk can support Win7 for AMS UMA systems.
]Is the AMD uma limited to < 4GB?
The RS780 frame buffer can be placed above 4GB. I remember booting a Tilapia board a while back and finding the frame buffer is above 4GB by default. A setup option can be used to select above or below.
]Thanks, ]Rudolf
