- When flashing a <acronym class="acronym">PIB</acronym> to the local device, the <acronym class="acronym">PIB</acronym> <acronym class="acronym">DAK</acronym> must match that of the local device or you will get a <span class="quote">“<span class="quote">DAK Not Zero</span>”</span> error message. This message is incorrect and should probably read <span class="quote">“<span class="quote">DAK Mismatch</span>”</span>. The following two toolkit commands should prevent this error from occuring on Linux. The first command reads the actual <acronym class="acronym">MAC</acronym> (<strong class="userinput"><code>-A</code></strong>) and <acronym class="acronym">DAK</acronym> (<strong class="userinput"><code>-D</code></strong>) from the device using program <a class="ulink" href="int6kid.7.html" target="_top">int6kid</a> and inserts them on the command lise as <a class="ulink" href="modpib.7.html" target="_top">modpib</a> arguments using options <strong class="userinput"><code>-M</code></strong> and <strong class="userinput"><code>-D</code></strong>. We need not include the station <acronym class="acronym">MAC</acronym> address on the <a class="ulink" href="int6k.7.html" target="_top">int6k</a> command line because the device is local, but we could include it.

- When flashing a <acronym class="acronym">PIB</acronym> to a remote device, the <acronym class="acronym">PIB</acronym> <acronym class="acronym">DAK</acronym> must be all zeros or you will get a <span class="quote">“<span class="quote">DAK Not Zero</span>”</span> error message. This message occurs because the <span class="productname">HomePlug</span>™ AV Specification does not permit a <acronym class="acronym">DAK</acronym> to be transmitted over powerline in any form. The following two toolkit commands should prevent this error on Linux. We must include the device <acronym class="acronym">MAC</acronym> on the command line when invoking each program because the device is remote. Notice that symbol <code class="constant">none</code> can be used as shorthand <code class="constant">00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00</code> when specifying the <acronym class="acronym">DAK</acronym>.

- The <acronym class="acronym">MAC</acronym> address stored in the <acronym class="acronym">PIB</acronym> can have any value but it is good practice to preserve the original value. This avoids the common mistake of flashing multiple network stations with the same <acronym class="acronym">MAC</acronym> address because the PIB was not updated.
