comment 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.

comment 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?

comment 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.
