No, this is the correct mailing list for your question (or use linux...@kvack.org). First you obtain a listing of your computer's valid memory map, either from Linux booting on it (maybe not so likely on your computer) or maybe from BIOS SETUP. With that information, you construct a kernel command line with multiple memmap= options. You can see an example of this here: http://lkml.indiana.edu/hypermail/linux/kernel/0809.1/0664.html Hope that helps you. -- ~Randy -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
