74two Installation CDs which are equally suitable to install Gentoo from, as long
75as you're planning on performing an Internet-based installation using the
76latest version of the available packages.

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>
378 359
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):
384</p>
385
386<pre caption="Testing disk performance">
387# <i>hdparm -tT /dev/hda</i>
388</pre>
389
390<p>
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):
394</p>
395
396<pre caption="Tweaking hard disk performance">

406<title>Optional: User Accounts</title>
407<body>
408
409<p>
410If you plan on giving other people access to your installation
411environment or you want to chat using <c>irssi</c> without root privileges (for
412security reasons), you need to create the necessary user accounts and change
413the root password.
414</p>
415
416<p>
417To change the root password, use the <c>passwd</c> utility:
418</p>
419
420<pre caption="Changing the root password">
421# <i>passwd</i>
422New password: <comment>(Enter your new password)</comment>
423Re-enter password: <comment>(Re-enter your password)</comment>
424</pre>
425
426<p>
427To create a user account, we first enter their credentials, followed by
428its password. We use <c>useradd</c> and <c>passwd</c> for these tasks.
429In the next example, we create a user called &quot;john&quot;.
430</p>
431
432<pre caption="Creating a user account">

436Re-enter password: <comment>(Re-enter john's password)</comment>
437</pre>
438
439<p>
440You can change your user id from root to the newly created user by using

452<body>
453
454<p>
455If you want to view the Gentoo Handbook (either from-CD or online) during the
456installation, make sure you have created a user account (see <uri
457link="#useraccounts">Optional: User Accounts</uri>). Then press <c>Alt-F2</c> to
458go to a new terminal and log in.
459</p>
460
461<p>
462If you want to view the documentation on the CD you can immediately run
463<c>lynx</c> to read it:

466<pre caption="Viewing the on-CD documentation">
467# <i>lynx /mnt/cdrom/docs/html/index.html</i>
468</pre>

470<p>
471However, it is preferred that you use the online Gentoo Handbook as it will be
472more recent than the one provided on the CD. You can view it using <c>lynx</c>
473as well, but only after having completed the <e>Configuring your Network</e>
474chapter (otherwise you won't be able to go on the Internet to view the
475document):

493If you want to allow other users to access your computer during the
494Gentoo installation (perhaps because those users are going to help you
495install Gentoo, or even do it for you), you need to create a user
496account for them and perhaps even provide them with your root password
497(<e>only</e> do that <e>if</e> you <b>fully trust</b> that user).
498</p>
499
500<p>
501To fire up the SSH daemon, execute the following command:
