324console during the installation, possibly boxes with no keyboard and
325screen attached. One allows you to boot 2.6 using the serial console and
326the other will do the same with our 2.4 kernel.

374When the Installation CD boots, it tries to detect all your hardware devices and
375loads the appropriate kernel modules to support your hardware. In the
376vast majority of cases, it does a very good job. However, in some cases it may
377not auto-load the kernel
378modules you need. If the PCI auto-detection missed some of your system's
379hardware, you will have to load the appropriate kernel modules manually.
380</p>
381
382<p>
383In the next example we try to load the <c>8139too</c> module (support for
384certain kinds of network interfaces):

395<body>
396 355
397<p>
398If you are an advanced user, you might want to tweak the IDE hard disk
399performance using <c>hdparm</c>. With the <c>-tT</c> options you can
400test the performance of your disk (execute it several times to get a
401more precise impression):

409To tweak, you can use any of the following examples (or experiment
410yourself) which use <path>/dev/hda</path> as disk (substitute with your
411disk):

425<p>
426If you plan on giving other people access to your installation
427environment or you want to chat using <c>irssi</c> without root privileges (for
428security reasons), you need to create the necessary user accounts and change
429the root password.
430</p>
431
432<p>
433To change the root password, use the <c>passwd</c> utility:
434</p>
435
436<pre caption="Changing the root password">

438New password: <comment>(Enter your new password)</comment>
439Re-enter password: <comment>(Re-enter your password)</comment>
440</pre>
441
442<p>
443To create a user account, we first enter their credentials, followed by
444its password. We use <c>useradd</c> and <c>passwd</c> for these tasks.
445In the next example, we create a user called &quot;john&quot;.
446</p>
447
448<pre caption="Creating a user account">

471If you want to view the Gentoo Handbook (either from-CD or online) during the
472installation, make sure you have created a user account (see <uri
473link="#useraccounts">Optional: User Accounts</uri>). Then press <c>Alt-F2</c> to
474go to a new terminal and log in.
475</p>
476
477<p>
478If you want to view the documentation on the CD you can immediately run
479<c>lynx</c> to read it:

487However, it is preferred that you use the online Gentoo Handbook as it will be
488more recent than the one provided on the CD. You can view it using <c>lynx</c>
489as well, but only after having completed the <e>Configuring your Network</e>
490chapter (otherwise you won't be able to go on the Internet to view the
491document):

509If you want to allow other users to access your computer during the
510Gentoo installation (perhaps because those users are going to help you
511install Gentoo, or even do it for you), you need to create a user
512account for them and perhaps even provide them with your root password
513(<e>only</e> do that <e>if</e> you <b>fully trust</b> that user).
514</p>
515

517To fire up the SSH daemon, execute the following command:
