title: Switch android x86 screen resolution
body: <p>I would like to use Android-x86 2.2 as an emulator on my Windows 7. I have downloaded VirtualBox and the ISO, and I've made a virtual machine with it, but I can't set the resolution to <code>320x480</code> or something similar.  </p>
  
  <p>The following tutorial "<a href="http://wayback.archive.org/web/20130202181045/http://androiddevnotes.com/2011/03/08/1299521520000.html">Using the Android-x86 Port as your Emulator</a>" suggests to insert:  </p>
  
  <pre class="lang-xml prettyprint-override"><code>&lt;ExtraDataItem name="CustomVideoMode2" value="320x480x16" /&gt;
  </code></pre>
  
  <p>to my <code>.vbox</code> file and I did it. Then I added <code>UVESA_MODE=320x480</code> and <code>vga=ask</code> to the boot config. When it boots, I have to press <kbd>Enter</kbd> to see the available options, but there is no <code>320x480</code> among them.  How can I get it to work?</p>
