357When the Installation CD boots, it tries to detect all your hardware devices and
358loads the appropriate kernel modules to support your hardware. In the
359vast majority of cases, it does a very good job. However, in some cases it may
360not auto-load the kernel
361modules you need. If the PCI auto-detection missed some of your system's
362hardware, you will have to load the appropriate kernel modules manually.
363</p>
364
365<p>
366In the next example we try to load the <c>8139too</c> module (support for
367certain kinds of network interfaces):

377<title>Optional: Tweaking Hard Disk Performance</title>
378<body>
379 355
380<p>
381If you are an advanced user, you might want to tweak the IDE hard disk
382performance using <c>hdparm</c>. With the <c>-tT</c> options you can
383test the performance of your disk (execute it several times to get a
384more precise impression):
385</p>
386
387<pre caption="Testing disk performance">
388# <i>hdparm -tT /dev/hda</i>
389</pre>
390
391<p>
392To tweak, you can use any of the following examples (or experiment
393yourself) which use <path>/dev/hda</path> as disk (substitute with your
394disk):
395</p>
396
397<pre caption="Tweaking hard disk performance">

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

437Re-enter password: <comment>(Re-enter john's password)</comment>
438</pre>
439
440<p>
441You can change your user id from root to the newly created user by using
442<c>su</c>:

453<body>
454
455<p>
456If you want to view the Gentoo Handbook (either from-CD or online) during the
457installation, make sure you have created a user account (see <uri
458link="#useraccounts">Optional: User Accounts</uri>). Then press <c>Alt-F2</c> to
459go to a new terminal and log in.
460</p>
461
462<p>
463If you want to view the documentation on the CD you can immediately run
464<c>lynx</c> to read it:
465</p>
466
467<pre caption="Viewing the on-CD documentation">
468# <i>lynx /mnt/cdrom/docs/html/index.html</i>
469</pre>
470
471<p>
472However, it is preferred that you use the online Gentoo Handbook as it will be
473more recent than the one provided on the CD. You can view it using <c>lynx</c>
474as well, but only after having completed the <e>Configuring your Network</e>
475chapter (otherwise you won't be able to go on the Internet to view the
476document):
477</p>
478
479<pre caption="Viewing the Online Documentation">

493<p>
494If you want to allow other users to access your computer during the
495Gentoo installation (perhaps because those users are going to help you
496install Gentoo, or even do it for you), you need to create a user
497account for them and perhaps even provide them with your root password
498(<e>only</e> do that <e>if</e> you <b>fully trust</b> that user).
499</p>
500
501<p>
502To fire up the SSH daemon, execute the following command:
