<para>If you are using a UEFI system instead of BIOS, the user interface is
slightly different as the boot device is obviously the EFI system Partition
(ESP).</para>

<para>This tool<footnote>
<para>You can start this tool from the command line, by typing <emphasis role="bold">drakboot</emphasis> as root.</para>
</footnote> allows you to configure the boot options (choice of the
bootloader, set a password, the default boot, etc.)</para>
<para>It is found under the Boot tab in the Mageia Control Center labeled
"Set up boot system".</para>
<warning>
<para>Don't use this tool if you don't know exactly what you are doing.
Changing some settings may prevent your machine from booting again
!</para>
</warning>
<para>In the first part, called <guilabel>Bootloader</guilabel>, it is
possible if using BIOS, to choose which <guibutton>Bootloader to
use</guibutton>, Grub, Grub2 or Lilo, and with a graphical or a text menu.
It is just a question of taste, there are no other consequences. You can
also set the <guibutton>Boot device</guibutton>, don't change anything here
unless you are an expert. The boot device is where the bootloader is
installed and any modification can prevent your machine from booting.</para>
<para>In a UEFI system, the bootloader is <guilabel>Grub2-efi</guilabel> and
is installed in /boot/EFI partition. This FAT32 formatted partition is
common to all operating systems installed.</para>
<para>In the second part, called <guilabel>Main options</guilabel>, you can
set the <guibutton>Delay before booting default image</guibutton>, in
seconds. During this delay, Grub or Lilo will display the list of available
operating systems, prompting you to make your choice. If no selection is
made, the bootloader will boot the default one once the delay
elapses.</para>
<para>In the third and last part, called <guibutton>Security</guibutton>, it
is possible to set a password for the bootloader. This means a username and
password will be asked at the boot time to select a booting entry or change
settings. The username is "root" and the password is the one chosen
here.</para>
<para>The <guibutton>Advanced</guibutton> button gives some extra
options.</para>
<para><guibutton>Enable ACPI:</guibutton></para>
<para>ACPI (Advanced Configuration and Power Interface) is a standard for
the power management. It can save energy by stopping unused devices, this
was the method used before APM. Check this box if your hardware is ACPI
compatible.</para>
<para><guibutton>Enable SMP:</guibutton></para>
<para>SMP stands for Symmetric Multi Processors, it's an architecture for
multicore processors.</para>
<note>
<para>If you have a processor with HyperThreading, Mageia will see it as a
dual processor and enable SMP.</para>
</note>
<para><guibutton>Enable APIC</guibutton> and <guibutton>Enable Local
APIC:</guibutton></para>
<para>APIC stands for Advanced Programmable Interrupt Controller. There are
two components in the Intel APIC system, the local APIC (LAPIC) and the I/O
APIC. The latter one routes the interrupts it receives from peripheral buses
to one or more local APICs that are in the processor. It is really useful
for multi-processor systems. Some computers have problems with the APIC
system which can cause freezes or incorrect device detection (error message
"spurious 8259A interrupt: IRQ7"). In this case, disable APIC and/or Local
APIC.</para>

<para>The <guibutton>Next</guibutton> screen differs depending on which boot
loader you chose.</para>
<itemizedlist>
<listitem>
<para>You have Grub Legacy or Lilo:</para>
<para>In this case, you can see the list of all the available entries at
boot time. The default one is asterisked. To change the order of the
menu entries, click on the up or down arrows to move the selected item.
If you click on the <guibutton>Add</guibutton> or
<guibutton>Modify</guibutton> buttons, a new window appears to add a new
entry in the bootloader menu or to modify an existing one. You need to
be familiar with Lilo or Grub to be able to use these tools.</para>

<imagedata fileref="drakboot2.png"/>
</imageobject>
</mediaobject>
<para>The <guilabel>Label</guilabel> field is freeform, write here what
you want to be displayed in the menu. It matches the Grub command
"title". For example: Mageia3.</para>
<para>The <guilabel>Image</guilabel> field contains the kernel name. It
matches the Grub command "kernel". For example /boot/vmlinuz.</para>
<para>The <guilabel>Root</guilabel> field contains the device name where
the kernel is stored. It matches the Grub command "root". For example
(hd0,1).</para>
<para>The <guilabel>Append</guilabel> field contains the options to be
given to the kernel at boot time.</para>
<para>If the box <guilabel>Default</guilabel> is checked, Grub will boot
this entry by default.</para>
<para>In the extra screen called <guilabel>Advanced</guilabel>, it is
possible to choose the <guilabel>Video mode</guilabel>, an
<guilabel>initrd</guilabel> file and a <guilabel>network
profile</guilabel>, see <xref linkend="draknetprofile"/>, in the
drop-down lists.</para>
</listitem>
<listitem>
<para>You have Grub2 or Grub2-efi (boot loaders used by default
respectively in Legacy mode and UEFI mode):</para>
<para>In this case, the drop-down list labelled
<guilabel>Default</guilabel> displays all the available entries; click
on the one wanted as the default one.</para>
<mediaobject>
<imageobject>
<imagedata fileref="drakboot3.png"/>
</imageobject>
</mediaobject>
<para>The <guilabel>Append</guilabel> field contains the options to be
given to the kernel at boot time.</para>
<para>If you have other operating systems installed, Mageia attempts to
add them to your Mageia boot menu. If you don't want this behaviour,
uncheck the box <guilabel>Probe Foreign OS</guilabel></para>
<para>In the extra screen called <guilabel>Advanced</guilabel>, it is
possible to choose the <guilabel>Video mode</guilabel>. If you don't
want a bootable Mageia, but to chain load it from another OS, check the
box <guilabel>Do not touch ESP or MBR</guilabel> and accept the
warning.</para>
<mediaobject>
<imageobject>
<imagedata fileref="drakboot6.png"/>
</imageobject>
</mediaobject>
<warning>
<para>Not installing on ESP or MBR means that the installation is not
bootable unless chain loaded from another OS.</para>
</warning>
<para>To set many other parameters, you can use the tool named
<emphasis>Grub Customizer</emphasis>, available in the Mageia
repositories (see below).</para>
