<h1 class="topictitle1">Set up virtual optical storage</h1>
<div><p>This topic provides a high-level overview of the steps used to
set up virtual optical storage. The topic also provides links to information
that provide specific instructions for setting up virtual optical storage
based on what task you want to accomplish.</p>
<div class="section"><p>The following provide a high-level overview of how to set up virtual
optical storage for the most common tasks. The exact steps you use to set
up virtual optical storage depend on what task you want to accomplish, such
as performing a save operation or distributing software.</p>
<p>The specific
tasks provide links to instructions for the different tasks that you can perform
with virtual optical storage.</p>
<p>The tasks are as follows:</p>
<ul><li><a href="#installimagecatalog">Install from an image catalog</a></li>
<li><a href="#create">Create virtual optical</a></li>
<li><a href="#use">Use virtual images in an image catalog</a></li>
