356When the Installation CD boots, it tries to detect all your hardware devices and
357loads the appropriate kernel modules to support your hardware. In the
358vast majority of cases, it does a very good job. However, in some cases it may
359not auto-load the kernel
360modules you need. If the PCI auto-detection missed some of your system's
361hardware, you will have to load the appropriate kernel modules manually.
362</p>
363
364<p>
365In the next example we try to load the <c>8139too</c> module (support for
366certain kinds of network interfaces):

377<body>
378 355
379<p>
380If you are an advanced user, you might want to tweak the IDE hard disk
381performance using <c>hdparm</c>. With the <c>-tT</c> options you can
382test the performance of your disk (execute it several times to get a
383more precise impression):

391To tweak, you can use any of the following examples (or experiment
392yourself) which use <path>/dev/hda</path> as disk (substitute with your
393disk):

407<p>
408If you plan on giving other people access to your installation
409environment or you want to chat using <c>irssi</c> without root privileges (for
410security reasons), you need to create the necessary user accounts and change
411the root password.
412</p>
413
414<p>
415To change the root password, use the <c>passwd</c> utility:

420New password: <comment>(Enter your new password)</comment>
421Re-enter password: <comment>(Re-enter your password)</comment>
422</pre>
423
424<p>
425To create a user account, we first enter their credentials, followed by
426its password. We use <c>useradd</c> and <c>passwd</c> for these tasks.
427In the next example, we create a user called &quot;john&quot;.
428</p>
429
430<pre caption="Creating a user account">

453If you want to view the Gentoo Handbook (either from-CD or online) during the
454installation, make sure you have created a user account (see <uri
455link="#useraccounts">Optional: User Accounts</uri>). Then press <c>Alt-F2</c> to
456go to a new terminal and log in.
457</p>
458
459<p>
460If you want to view the documentation on the CD you can immediately run

469However, it is preferred that you use the online Gentoo Handbook as it will be
470more recent than the one provided on the CD. You can view it using <c>lynx</c>
471as well, but only after having completed the <e>Configuring your Network</e>

491If you want to allow other users to access your computer during the
492Gentoo installation (perhaps because those users are going to help you
493install Gentoo, or even do it for you), you need to create a user
494account for them and perhaps even provide them with your root password
495(<e>only</e> do that <e>if</e> you <b>fully trust</b> that user).
496</p>
497
