Hi,

I've had a look through the list archives and can't find any relevant (64bit) posts. My 64 bit Xen install is only showing 3194MB of the 4x1GB RAM installed. The BIOS shows all 4GB on boot. It's an Intel Desktop board (I forget the model and don't currently have physical access) with a hyper threading Pentium 4 CPU. Any ideas or explanations would be most welcome.

Thanks,

Simon
