I have a Dell Precision Workstation 470 with an Intel Xeon CPU. I've loaded VMWare ESX 3i v3.5.0 on it and can load 32 bit Windows Server 2003 but I can't load the 64 bit version. Windows tells me that my CPU is not compatible with 64 bit mode

I just removed Windows XP Pro 64bit from it (to test VMWare) so I know that it does run 64 bit software

Your CPU may be 64 bit compatible which means that it can support 64 bit operating system. To support 64 bit virtual machines your CPU and BIOS must support Intel Virtualization.  If your CPU and/or BIOS does not support virtualization you will not be able to run 64 bit virtual machines.

To validate this, download CPUID application at the url below and burn to CD to run
