396When the Installation CD boots, it tries to detect all your hardware devices and
397loads the appropriate kernel modules to support your hardware. In the vast
398majority of cases, it does a very good job. However, in some cases it may not
399auto-load the kernel modules you need. If the PCI auto-detection missed some of
400your system's hardware, you will have to load the appropriate kernel modules
401manually.
402</p>
403
404<p>
405In the next example we try to load the <c>8139too</c> module (support for
406certain kinds of network interfaces):

416<title>Optional: Tweaking Hard Disk Performance</title>
417<body>
418 395
419<p>
420If you are an advanced user, you might want to tweak the IDE hard disk
421performance using <c>hdparm</c>. With the <c>-tT</c> options you can
422test the performance of your disk (execute it several times to get a
423more precise impression):
424</p>
425
426<pre caption="Testing disk performance">
427# <i>hdparm -tT /dev/hda</i>
428</pre>
429
430<p>
431To tweak, you can use any of the following examples (or experiment
432yourself) which use <path>/dev/hda</path> as disk (substitute with your
433disk):
434</p>
435
436<pre caption="Tweaking hard disk performance">
437<comment>Activate DMA:</comment>
438# <i>hdparm -d 1 /dev/hda</i>
439<comment>Activate DMA + Safe Performance-enhancing Options:</comment>
440# <i>hdparm -d 1 -A 1 -m 16 -u 1 -a 64 /dev/hda</i>

446<title>Optional: User Accounts</title>
447<body>
448
449<p>
450If you plan on giving other people access to your installation
451environment or you want to chat using <c>irssi</c> without root privileges (for
452security reasons), you need to create the necessary user accounts and change
453the root password.
454</p>
455
456<p>
457To change the root password, use the <c>passwd</c> utility:
458</p>
459
460<pre caption="Changing the root password">
461# <i>passwd</i>
462New password: <comment>(Enter your new password)</comment>
463Re-enter password: <comment>(Re-enter your password)</comment>
464</pre>
465
466<p>
467To create a user account, we first enter their credentials, followed by
468its password. We use <c>useradd</c> and <c>passwd</c> for these tasks.
469In the next example, we create a user called &quot;john&quot;.
470</p>
471
472<pre caption="Creating a user account">
473# <i>useradd -m -G users john</i>
474# <i>passwd john</i>
475New password: <comment>(Enter john's password)</comment>
476Re-enter password: <comment>(Re-enter john's password)</comment>
477</pre>
478
479<p>
480You can change your user id from root to the newly created user by using
481<c>su</c>:
482</p>
483
484<pre caption="Changing user id">
485# <i>su - john</i>

491<title>Optional: Viewing Documentation while Installing</title>
492<body>
493
494<p>
495If you want to view the Gentoo Handbook during the installation, make sure you
496have created a user account (see <uri link="#useraccounts">Optional: User
497Accounts</uri>). Then press <c>Alt-F2</c> to go to a new terminal and log in.
498</p>
499
500<p>
501If you want to view the documentation on the CD you can immediately run
502<c>links</c> to read it:
503</p>
504
505<pre caption="Viewing the on-CD documentation">
506# <i>links /mnt/cdrom/docs/handbook/html/index.html</i>
507</pre>
508
509<p>
510However, it is preferred that you use the online Gentoo Handbook as it will be
511more recent than the one provided on the CD.
512</p>
513
514<pre caption="Viewing the Online Documentation">
515# <i>links http://www.gentoo.org/doc/en/handbook/<keyval id="online-book"/></i>
516</pre>
517
518<p>
519You can go back to your original terminal by pressing <c>Alt-F1</c>.

525<title>Optional: Starting the SSH Daemon</title>
526<body>
527
528<p>
529If you want to allow other users to access your computer during the
530Gentoo installation (perhaps because those users are going to help you
531install Gentoo, or even do it for you), you need to create a user
532account for them and perhaps even provide them with your root password
533(<e>only</e> do that <e>if</e> you <b>fully trust</b> that user).
534</p>
535
536<p>
537To fire up the SSH daemon, execute the following command:
538</p>
539
540<pre caption="Starting the SSH daemon">
541# <i>/etc/init.d/sshd start</i>
542</pre>
543
544<p>
545To be able to use sshd, you first need to set up your networking. Continue with
546the chapter on <uri link="?part=1&amp;chap=3">Configuring your Network</uri>.
