title: What does mov(%edx, %ebx, 1), %al do?
body: <p>I am trying to figure out a binary bomb lab, phase 5.  This is not a homework assignment but rather something I am doing on my own. </p>
  
  <p>I found a similar question answered <a href="https://stackoverflow.com/questions/14900343/how-does-mov-ebx-eax-4-eax-work?rq=1">here</a> but I didn't understand the answer since there actual values were not plugged in.  I am trying to figure out what, exactly, ends up in %al, assuming that %al is the destination.  I am using gdb and the i r command showed that %ebx holds the string I entered for input, which was "device", and %edx has 0. What does this do?</p>
