One of the first things I did was try to see if the BIOS had an upgrade, but the BIOS has the last posted upgrade that I can find, R1.28VH.
I am basing my problem on the fact that I see only 2.67 GB available in my 64bit install of Linux CentOS. I think that XP Pro is not capable of using 4GB of memory and so seeing that amount available in XP Pro is not the source of my concern. I was expecting the 64 bit Linux to use all 4GB even if XP Pro would not. Is it possible that the 64 bit Linux is just not using the memory and the motherboard is not at fault at all?
