34<H2>Description</H2>
35<P>Set the area that should not be cleared by <a href="../Init/OSInit.html"><code>OSInit</code></a> after <code><a href="OSExec.html">OSExecl</a></code>/<code><a href="OSExec.html">OSExecv</a></code>. By default, <a href="../Init/OSInit.html"><code>OSInit</code></a> clears all the arena, but if you call this function, you can leave [<i><code>start</code></i>, <i><code>end</code></i>) uncleared. Note that this function operates on only <a href="../Init/OSInit.html"><code>OSInit</code></a> after <code><a href="OSExec.html">OSExecl</a></code>/<code><a href="OSExec.html">OSExecv</a></code>.</P>
36<P>[<i><code>start</code></i>, <i><code>end</code></i>) must be included in the area [0x8070_0000, 0x8120_0000) (i.e., <i><code>start</code></i> must be larger than or equal to 0x8070_0000 and <i><code>end</code></i> must be smaller than or equal to 0x8120_0000). If NULLs are specified, the default action will be taken, i.e., <a href="../Init/OSInit.html"><code>OSInit</code></a> will clear the arena.</P>
