Hi
I have a Dell D820 w. 1 GB RAM.
When I try to install Vista and the computer is loading the DVD - I'am
told that the pc/cpu is not able to load a 64 bit appl.
It is a Intel T2500 @ 2.0 Ghz. CPU.
I have tryed to change/setup the BIOS (version 7) any posible way.
Have anyone tryed to install Vista x64 on a Dell D820? Please help...
