title: Hooking x86 reset vector
body: <p>Is it possible to hook the x86 CPU reset vector? (386+, since on the lower ones it's trivial) If so, how could it be done? If not, why does Linux (I've seen a distro) in text mode, in the same terminal as the syslog, show quite a lot of text right in the moment I push the reset button?</p>
  
  <p>I would like to hook that in my future OS, if possible... (like making RESET trigger something similar to Windows' BSOD and dump memory before actually resetting, something something)</p>
