+mkrd [-m &lt;minor&gt;] [-s &lt;sector-size&gt;] &lt;nsectors&gt;

+<p>
+  <b>Synopsis</b>.
+  Create a ramdisk consisting of <code>&lt;nsectors&gt;</code>, each of size
+  <code>&lt;sector-size&gt;</code> (or 512 bytes if <code>&lt;sector-size&gt;</code> is not specified.
+  The ramdisk will be registered as <code>/dev/ram&lt;n&gt;</code> (if <code>&lt;n&gt;</code> is not
+  specified, mkrd will attempt to register the ramdisk as <code>/dev/ram0</code>.
+</p>
+<p><b>Example</b></p>
+<ul><pre>
+nsh&gt; ls /dev
+/dev:
+ console
+ null
+ ttyS0
+ ttyS1
+nsh&gt; mkrd 1024
+nsh&gt; ls /dev
+/dev:
+ console
+ null
+ ram0
+ ttyS0
+ ttyS1
+nsh&gt;
+</pre></ul>
+<p>
+  Once the ramdisk has been created, it may be formatted using
+  the <code>mkfatfs</code> command and mounted using the <code>mount</code> command.
+</p>
+<p><b>Example</b></p>
+<ul><pre>
+nsh&gt; mkrd 1024
