<para>If you are using a UEFI system instead of BIOS, the user interface is
slightly different as you cannot choose the boot loader (first drop down
list) since only one is available.</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 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.</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. This one routes the interrupts it receives them 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 whether you have
an <emphasis>BIOS</emphasis> or <emphasis>UEFI</emphasis> system.</para>
<itemizedlist>
<listitem>
<para>You have a <emphasis>BIOS</emphasis> system:</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>

<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 a <emphasis>UEFI</emphasis> system:</para>
<para>In this case, the drop-down list displays all the available entries; click
on the one wanted as the default one.</para>

the kernel at boot time.</para>
<para>In the extra screen called <guilabel>Advanced</guilabel>, it is possible to
choose the <guilabel>Video mode</guilabel>.</para>
<para>To set many other parameters, you can use <emphasis>Grub
Customize</emphasis>r, available in the Mageia repositories (see below).</para>
