431When the Installation CD boots, it tries to detect all your hardware devices and
432loads the appropriate kernel modules to support your hardware. In the
433vast majority of cases, it does a very good job. However, in some cases, it may
434not auto-load the kernel modules you need. If the PCI auto-detection missed some
435of your system's hardware, you will have to load the appropriate kernel modules
436manually.
437</p>
438
439<p>
440In the next example we try to load the <c>airport</c> module. This module
441supports only the old Airport cards (802.11b). Airport Extreme (802.11g) is not
442supported on the InstallCD due to restrictions on firmware distribution.

450On older iMacs, sometimes the network card is not detected properly. These use
451the BMAC driver:

461<title>Optional: Tweaking Hard Disk Performance</title>
462<body>
463 430
464<p>
465If you are an advanced user, you might want to tweak the IDE hard disk
466performance using <c>hdparm</c>. With the <c>-tT</c> options you can
467test the performance of your disk (execute it several times to get a
468more precise impression):
469</p>
470
471<pre caption="Testing disk performance">
472# <i>hdparm -tT /dev/hda</i>
473</pre>
474
475<p>
476To tweak, you can use any of the following examples (or experiment
477yourself) which use <path>/dev/hda</path> as disk (substitute with your
478disk):
479</p>
480
481<pre caption="Tweaking hard disk performance">
482<comment>Activate DMA:</comment>
483# <i>hdparm -d 1 /dev/hda</i>
484<comment>Activate DMA + Safe Performance-enhancing Options:</comment>

491<title>Optional: User Accounts</title>
492<body>
493
494<p>
495If you plan on giving other people access to your installation
496environment or you want to chat using <c>irssi</c> without root privileges (for
497security reasons), you need to create the necessary user accounts and change
498the root password.
499</p>
500
501<p>
502To change the root password, use the <c>passwd</c> utility:
503</p>
504
505<pre caption="Changing the root password">
506# <i>passwd</i>
507New password: <comment>(Enter your new password)</comment>
508Re-enter password: <comment>(Re-enter your password)</comment>
509</pre>
510
511<p>
512To create a user account, we first enter their credentials, followed by
513its password. We use <c>useradd</c> and <c>passwd</c> for these tasks.
514In the next example, we create a user called &quot;john&quot;.
515</p>
516
517<pre caption="Creating a user account">
518# <i>useradd -m -G users john</i>
519# <i>passwd john</i>
520New password: <comment>(Enter john's password)</comment>
521Re-enter password: <comment>(Re-enter john's password)</comment>
522</pre>
523
524<p>
525You can change your user id from root to the newly created user by using
526<c>su</c>:
527</p>
528
529<pre caption="Changing user id">
530# <i>su - john</i>

536<title>Optional: Viewing Documentation while Installing</title>
537<body>
538
539<p>
540If you want to view the Gentoo Handbook (either from-CD or online) during the
541installation, make sure you have created a user account (see <uri
542link="#useraccounts">Optional: User Accounts</uri>). Then press <c>Alt-F2</c> to
543go to a new terminal and log in.
544</p>
545
546<p>
547If you want to view the documentation on the CD you can immediately run
548<c>links</c> or even <c>links -g</c> for a graphical framebuffer browser to
549read it:
550</p>
551
552<pre caption="Viewing the on-CD documentation">
553# <i>links /mnt/cdrom/docs/html/index.html</i>
554</pre>
555
556<p>
557However, it is preferred that you use the online Gentoo Handbook as it will be
558more recent than the one provided on the CD. You can view it using <c>links</c>
559as well, but only after having completed the <e>Configuring your Network</e>
560chapter (otherwise you won't be able to go on the Internet to view the
561document):
562</p>
563
564<pre caption="Viewing the Online Documentation">
565# <i>links http://www.gentoo.org/doc/en/handbook/<keyval id="online-book"/></i>
566</pre>
567
568<p>
569You can go back to your original terminal by pressing <c>Alt-F1</c>.

575<title>Optional: Starting the SSH Daemon</title>
576<body>
577
578<p>
579If you want to allow other users to access your computer during the
580Gentoo installation (perhaps because those users are going to help you
581install Gentoo, or even do it for you), you need to create a user
582account for them and perhaps even provide them with your root password
583(<e>only</e> do that <e>if</e> you <b>fully trust</b> that user).
584</p>
585
586<p>
587To fire up the SSH daemon, execute the following command:
588</p>
589
590<pre caption="Starting the SSH daemon">
591# <i>/etc/init.d/sshd start</i>
592</pre>
593
594<p>
595To be able to use sshd, you first need to set up your networking. Continue with
596the chapter on <uri link="?part=1&amp;chap=3">Configuring your Network</uri>.
