  10. 				The <span class="productname">INT6300</span>™ and <span class="productname">INT6400</span>™ do not require a special <acronym class="acronym">SDRAM</acronym> configuration file and so program <a class="ulink" href="int6kboot.7.html" target="_top">int6kboot</a> may be used in place of <a class="ulink" href="int6kf.7.html" target="_top">int6kf</a> which is described here. The only real difference between the two programs is the presence or absence of option <span class="command"><strong>-C</strong></span> on the command line.

  12. 			The <a class="ulink" href="int6kf.7.html" target="_top">int6kf</a> program can program a blank or corrupted <acronym class="acronym">NVRAM</acronym> on the INT6300. The process involves starting the runtime firmware as shown in the previous example then downloading a .nvm file using a <code class="constant">VS_WR_MOD</code> message, downloading a .pib file using another WR_WR_MOD message then writing both to <acronym class="acronym">NVRAM</acronym> using a <code class="constant">VS_MOD_NVM</code> message. An example <a class="ulink" href="int6kf.7.html" target="_top">int6kf</a> command line is shown below. It is identical to the one shown above except for the addition of the flash option at the end.

  18. 			The example above starts the firmware then uses it to program the <acronym class="acronym">NVRAM</acronym>. This was done in one step rather than two seperate steps as shown in the examples before it. The only difference is that <span class="command"><strong>int6k</strong></span> needs to use the 'force flash' option when using downloaded firmware to write <acronym class="acronym">NVRAM</acronym>. The following example accomplishes the same thing as the previous example but uses <span class="command"><strong>int6k</strong></span> to program <acronym class="acronym">NVRAM</acronym>. See the <a class="ulink" href="int6k.7.html" target="_top">int6k</a> man page for an explanation of the command line options and arguments used here.

  20. 			The <a class="ulink" href="int6kf.7.html" target="_top">int6kf</a> program cannot program blank or corrupted <acronym class="acronym">NVRAM</acronym> on the INT6000 unless the <span class="application">Softloader</span> is running. Since the <span class="application">Softloader</span> resides in <acronym class="acronym">NVRAM</acronym>, the NVRAM must be either pre-programmed before use or removed and externally re-programmed if it corrupts.
