I have updated my BIOS to the latest version and also attempted the msconfig, boot, advanced fix and neither has worked. So what gives? Why can't I use the other gig of RAM I have installed? I understand my chipset (Intel 945) is integrated so it is natural for it to pull operating memory, but not a whole gig! I can't see where I can remap in BIOS to have it use less than this. How do I proceed? I want to ave use of the remaining gig of memory.
