DHCP configuration for iPXE Sorry I was a bit unclear. But what I want is to configure iPXE to issue its DHCP discover message to include more options, so my DHCP server can give out those options in its response message. |

Using dd to cause an error in memory I see. Thanks. In the document (the Nehalem part), it mentions about using address match for error injection . What does it do? Does it mean, by using address match, it will cause an error at that specific physical memory address that is specified in address match register? And if edac hardware is working, when that faulty memory address is read, it should correct the error. Is that right? |

Using dd to cause an error in memory So how does dd trigger a memory error exactly? I understand the inject things are for the configuration of error injection registers: lxr.linux.no/#linux+v3.0.42/drivers/edac/i7core_edac.c#L963 . The values the inject interfaces will be anded with each other and write to a register. But I don't understand how using dd can trigger error in memory. |

How can I generate /proc/vmcore? Thanks. Our system uses SLES (SUSE Linux Enterprise Server), and it generates vmcore. I just want to know how it is generated in a standard way. But since you mention this is kernel specific, I will look into the specific documents. |

What are high memory and low memory on Linux? This is old and I'm not sure you're around here. But I want to ask one thing: the reserved 128MB in kernel space (for high memory access), is it all the references of user-space memory area? So, a kernel process can access any user space by refer to this area, right? |

No vmlinuz and initrd after building the kernel? Thanks. You are correct. |
