492When the Installation CD boots, it tries to detect all your hardware devices and
493loads the appropriate kernel modules to support your hardware. In the
494vast majority of cases, it does a very good job. However, in some cases, it may
495not auto-load the kernel modules you need. If the PCI auto-detection missed some
496of your system's hardware, you will have to load the appropriate kernel modules
497manually.

517If you are an advanced user, you might want to tweak the IDE hard disk
518performance using <c>hdparm</c>. With the <c>-tT</c> options you can
519test the performance of your disk (execute it several times to get a
520more precise impression):

528To tweak, you can use any of the following examples (or experiment

530disk):

544<p>
545If you plan on giving other people access to your installation

547security reasons), you need to create the necessary user accounts and change
548the root password.
549</p>
550
551<p>
552To change the root password, use the <c>passwd</c> utility:

558Re-enter password: <comment>(Re-enter your password)</comment>
559</pre>
560
561<p>
562To create a user account, we first enter their credentials, followed by
563its password. We use <c>useradd</c> and <c>passwd</c> for these tasks.
564In the next example, we create a user called &quot;john&quot;.

590If you want to view the Gentoo Handbook (either from-CD or online) during the

593go to a new terminal and log in.

607more recent than the one provided on the CD. You can view it using <c>links2</c>
608as well, but only after having completed the <e>Configuring your Network</e>

631account for them and perhaps even provide them with your root password
