Some installation problems can be avoided or alleviated by updating the firmware on various hardware components, most notably the motherboard. Motherboard firmware is usually referred to as the <acronym>BIOS</acronym>. Most motherboard and computer manufacturers have a website for upgrades and upgrade information.
Manufacturers generally advise against upgrading the motherboard <acronym>BIOS</acronym> unless there is a good reason for doing so, like a critical update. The upgrade process <emphasis>can</emphasis> go wrong, leaving the <acronym>BIOS</acronym> incomplete and the computer inoperative.
If the system hangs while probing hardware during boot, or it behaves strangely during install, <acronym>ACPI</acronym> may be the culprit. FreeBSD makes extensive use of the system <acronym>ACPI</acronym> service on the i386 and amd64 platforms to aid in system configuration if it is detected during boot. Unfortunately, some bugs still exist in both the <acronym>ACPI</acronym> driver and within system motherboards and <acronym>BIOS</acronym> firmware. <acronym>ACPI</acronym> can be disabled by setting the <literal>hint.acpi.0.disabled</literal> hint in the third stage boot loader:
<userinput>set hint.acpi.0.disabled="1"</userinput>
This is reset each time the system is booted, so it is necessary to add <literal>hint.acpi.0.disabled="1"</literal> to the file <filename>/boot/loader.conf</filename>. More information about the boot loader can be found in <xref linkend="boot-synopsis"/>.
Using the Live <acronym>CD</acronym>
The welcome menu of <application>bsdinstall</application>, shown in <xref linkend="bsdinstall-choose-mode"/>, provides a <guibutton>[ Live CD ]</guibutton> option. This is useful for those who are still wondering whether FreeBSD is the right operating system for them and want to test some of the features before installing.
The following points should be noted before using the <guibutton>[ Live CD ]</guibutton>:
To gain access to the system, authentication is required. The username is <systemitem class="username">root</systemitem> and the password is blank.
As the system runs directly from the installation media, performance will be significantly slower than that of a system installed on a hard disk.
This option only provides a command prompt and not a graphical interface.
FreeBSD Basics
This chapter covers the basic commands and functionality of the FreeBSD operating system. Much of this material is relevant for any <trademark class="registered">UNIX</trademark>-like operating system. New FreeBSD users are encouraged to read through this chapter carefully.
How to use and configure virtual consoles.
How to create and manage users and groups on FreeBSD.
How <trademark class="registered">UNIX</trademark> file permissions and FreeBSD file flags work.
The default FreeBSD file system layout.
The FreeBSD disk organization.
How to mount and unmount file systems.
What processes, daemons, and signals are.
What a shell is, and how to change the default login environment.
How to use basic text editors.
What devices and device nodes are.
How to read manual pages for more information.
Virtual Consoles and Terminals
<primary>virtual consoles</primary>
Unless FreeBSD has been configured to automatically start a graphical environment during startup, the system will boot into a command line login prompt, as seen in this example:
FreeBSD/amd64 ( (ttyv0)

The first line contains some information about the system. The <literal>amd64</literal> indicates that the system in this example is running a 64-bit version of FreeBSD. The hostname is <systemitem></systemitem>, and <filename>ttyv0</filename> indicates that this is the <quote>system console</quote>. The second line is the login prompt.
