341The default Alpha profile uses nptl and requires a 2.6 kernel. If your system
342cannot support nptl (or you do not want to use nptl), you should use the 2.4
343kernel. Alternatively, if you prefer to compile your system without nptl, you
344will be given the chance to select a stage built without nptl in <uri

365When the Installation CD boots, it tries to detect all your hardware devices and
366loads the appropriate kernel modules to support your hardware. In the
367vast majority of cases, it does a very good job. However, in some cases it may
368not auto-load the kernel
369modules you need. If the PCI auto-detection missed some of your system's
370hardware, you will have to load the appropriate kernel modules manually.
371</p>
372
373<p>
374In the next example we try to load the <c>8139too</c> module (support for
375certain kinds of network interfaces):

385<title>Optional: Tweaking Hard Disk Performance</title>
386<body>
387 355
388<p>
389If you are an advanced user, you might want to tweak the IDE hard disk
390performance using <c>hdparm</c>. With the <c>-tT</c> options you can
391test the performance of your disk (execute it several times to get a
392more precise impression):

394
395<pre caption="Testing disk performance">
396# <i>hdparm -tT /dev/hda</i>
397</pre>
398
399<p>
400To tweak, you can use any of the following examples (or experiment
401yourself) which use <path>/dev/hda</path> as disk (substitute with your
402disk):

414<body>
415
416<p>
417If you plan on giving other people access to your installation
418environment or you want to chat using <c>irssi</c> without root privileges (for
419security reasons), you need to create the necessary user accounts and change
420the root password.
421</p>
422
423<p>
424To change the root password, use the <c>passwd</c> utility:
425</p>
426
427<pre caption="Changing the root password">
428# <i>passwd</i>
429New password: <comment>(Enter your new password)</comment>
430Re-enter password: <comment>(Re-enter your password)</comment>
431</pre>
432
433<p>
434To create a user account, we first enter their credentials, followed by
435its password. We use <c>useradd</c> and <c>passwd</c> for these tasks.
436In the next example, we create a user called &quot;john&quot;.
437</p>
438
439<pre caption="Creating a user account">

443Re-enter password: <comment>(Re-enter john's password)</comment>
444</pre>
445
446<p>
447You can change your user id from root to the newly created user by using

462If you want to view the Gentoo Handbook (either from-CD or online) during the
463installation, make sure you have created a user account (see <uri
464link="#useraccounts">Optional: User Accounts</uri>). Then press <c>Alt-F2</c> to
465go to a new terminal and log in.
466</p>
467
468<p>
469If you want to view the documentation on the CD you can immediately run
470<c>lynx</c> to read it:

478However, it is preferred that you use the online Gentoo Handbook as it will be
479more recent than the one provided on the CD. You can view it using <c>lynx</c>
480as well, but only after having completed the <e>Configuring your Network</e>
481chapter (otherwise you won't be able to go on the Internet to view the
482document):

500If you want to allow other users to access your computer during the
501Gentoo installation (perhaps because those users are going to help you
502install Gentoo, or even do it for you), you need to create a user
503account for them and perhaps even provide them with your root password
504(<e>only</e> do that <e>if</e> you <b>fully trust</b> that user).
505</p>
506
