(I have asked Debian users, they don't seem to know) kernel 2.4/2.6 fail to boot on my PC probably because it can't detect my memory so I have to tell kernel memory map the following is copied from kernel-parameters.txt: memmap=exactmap [KNL,X86] Enable setting of an exact E820 memory map, as specified by the user. Such memmap=exactmap lines can be constructed based on BIOS output or other requirements. See the memmap=nn@ss option description. Could you tell me how to construct memmap= lines? -- To unsubscribe from this list: send the line "unsubscribe linux-x86_64" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
