<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

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>
