<div><p>When you perform a manual IPL on your system, the IPL or Install
|
|
the System menu provides an option to install the operating system.</p>
|
|
<div class="p">The dedicated service tools (DST) function provides the ability to require
|
|
anyone using this menu option to enter the DST security password. You can
|
|
use this to prevent someone from restoring an unauthorized copy of the operating
|
|
system. To secure the installation of your operating system, do the following: <ol><li>Perform a manual IPL.</li>
|
|
<li>From the IPL or Install the System menu, select DST. </li>
|
|
<li>From the Use DST menu, select the option to work with the DST environment.</li>
|
|
<li>Select the option to change DST passwords. </li>
|
|
<li>Select the option to change the operating system install security.</li>
|
|
<li>Specify 1 (secure). </li>
|
|
<li>Press F3 (exit) until you return to the IPL or Install the System menu.</li>
|
|
<li>Complete the manual IPL and return the keylock to its normal position.</li>
|
|
</ol>
|
|
<div class="note"><span class="notetitle">Note:</span> <ol><li>If you no longer want to secure the installation of the operating system,
|
|
follow the same steps and specify 2 (not secure).</li>
|
|
<li>You can also prevent installation of the operating system by keeping your
|
|
keylock switch in the normal position and removing the key.</li>
