cluberti Posted November 16, 2006 Share Posted November 16, 2006 Check out KB's 279151 and 822842 for a hint of what's happening. Basically, the BIOS will reserve RAM for shadowing or buffer (for things like hot-add memory, PCI-X bus, video shadowing, etc), and when we boot up, we do check to see if the BIOS has reserved memory.If you run msinfo32, you'll probably see the correct amount of RAM installed in your system displayed, as this amount is displayed as the result of WMI calls to the BIOS for the physical amount of installed RAM (regardless of reservation) - however, the amount on the general tab shows you how much Windows can and is actually using. If you've got Windows Server 2000 Advanced edition or Server 2003 Enterprise, you can add the /3GB switch and possibly see all of the memory in the general tab, but this is not recommended as attempting to use memory reserved by the BIOS results in system instability.
