Fortunately you can use a real processor with 4GB of RAM as well as an IA-64 (if you can find one even!). It is chipset dependant whether RAM lost to the PCI window can be made to appear over the 4GB boundary with a PAE capable intel ia32 processor (or clone) with an AMD x86-64 processor (or clone) It depends entirely on the chipset quality - 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/
