Yeah. Bios doesn't recognize the 4th gb of memory with the remapping enabled in bios and the remapping doesn't seem to work with PAE or x86_64. I've contacted customer support at asus and hope...they can get a bios that will let me do a x86_64 install that will recognize all my memory. The current bios is only a month old and actually in beta and was released for windows to address this problem on a 64 bit system. Their remapping scheme seems to fail under linux though unless there is something I don't know about. Shawn
