Processor information
I get only 3 GB RAM even if I have 4 GB RAM installed.
When I try to install or run a 64 bit OS, the system reboots, over and over.
I've observed that the system reboots at the stage "Loading modules".
If I add the boot parameter "mem=4096m" everything is fine, except that I get
only 3 GB RAM.
If I add the boot parameter "acpi=off" I get the 4 GB RAM, but after a few
minutes the system reboots.
