Well, maybe. I mean, the CPUs all have PAE (in 32-bit mode) and thus can use 36-bit physical addressing these days (or more in the case of amd chips).

Hrm, it may be doing this. I wonder how that works though with 4GB's of RAM installed?
I originally thought Windows probably allowed the larger addresses and use PAE but that might not be the case at all. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
