For this architecture the &d-i; supports two different user interfaces: a character-based one and a graphical one. The character-based interface is used by default unless you selected the <quote>Graphical install</quote> option in the initial boot menu. For more information about the graphical installer, please refer to <xref linkend="graphical"/>.

For this architecture the installer uses a character-based user interface. A graphical user interface is currently not available.

11.

In the character-based environment the use of a mouse is not supported. Here are the keys you can use to navigate within the various dialogs. The <keycap>Tab</keycap> or <keycap>right</keycap> arrow keys move <quote>forward</quote>, and the <keycombo> <keycap>Shift</keycap> <keycap>Tab</keycap> </keycombo> or <keycap>left</keycap> arrow keys move <quote>backward</quote> between displayed buttons and selections. The <keycap>up</keycap> and <keycap>down</keycap> arrow select different items within a scrollable list, and also scroll the list itself. In addition, in long lists, you can type a letter to cause the list to scroll directly to the section with items starting with the letter you typed and use <keycap>Pg-Up</keycap> and <keycap>Pg-Down</keycap> to scroll the list in sections. The <keycap>space bar</keycap> selects an item such as a checkbox. Use &enterkey; to activate choices.

During hardware detection &d-i; checks if any of the drivers for the hardware devices in your system require firmware to be loaded. If any firmware is requested but unavailable, a dialog will be displayed that allows the missing firmware to be loaded from a removable medium. See <xref linkend="loading-firmware"/> for further details.

If you selected a language that is recognized as an official language for more than one country<footnote> <para> In technical terms: where multiple locales exist for that language with differing country codes. </para> </footnote>, you will be shown a list of only those countries. To select a country that is not in that list, choose <guimenuitem>Other</guimenuitem> (the last option). You will then be presented with a list of continents; selecting a continent will lead to a list of relevant countries on that continent.

90.

If the language has only one country associated with it, that country will be selected automatically. In that case it is only possible to select a different country by first lowering the debconf priority to medium, followed by revisiting the language selection option in the main menu of the installer.

If you have more than one harddrive<footnote><para> To be honest, you can construct an MD device even from partitions residing on single physical drive, but that won't give any benefits. </para></footnote> in your computer, you can use <command>mdcfg</command> to set up your drives for increased performance and/or better reliability of your data. The result is called <firstterm>Multidisk Device</firstterm> (or after its most famous variant <firstterm>software RAID</firstterm>).

What benefits this brings depends on the type of MD device you are creating. Currently supported are: <variablelist> <varlistentry> <term>RAID0</term><listitem><para> Is mainly aimed at performance. RAID0 splits all incoming data into <firstterm>stripes</firstterm> and distributes them equally over each disk in the array. This can increase the speed of read/write operations, but when one of the disks fails, you will lose <emphasis>everything</emphasis> (part of the information is still on the healthy disk(s), the other part <emphasis>was</emphasis> on the failed disk). </para><para> The typical use for RAID0 is a partition for video editing. </para></listitem> </varlistentry> <varlistentry> <term>RAID1</term><listitem><para> Is suitable for setups where reliability is the first concern. It consists of several (usually two) equally-sized partitions where every partition contains exactly the same data. This essentially means three things. First, if one of your disks fails, you still have the data mirrored on the remaining disks. Second, you can use only a fraction of the available capacity (more precisely, it is the size of the smallest partition in the RAID). Third, file-reads are load-balanced among the disks, which can improve performance on a server, such as a file server, that tends to be loaded with more disk reads than writes. </para><para> Optionally you can have a spare disk in the array which will take the place of the failed disk in the case of failure. </para></listitem> </varlistentry> <varlistentry> <term>RAID5</term><listitem><para> Is a good compromise between speed, reliability and data redundancy. RAID5 splits all incoming data into stripes and distributes them equally on all but one disk (similar to RAID0). Unlike RAID0, RAID5 also computes <firstterm>parity</firstterm> information, which gets written on the remaining disk. The parity disk is not static (that would be called RAID4), but is changing periodically, so the parity information is distributed equally on all disks. When one of the disks fails, the missing part of information can be computed from remaining data and its parity. RAID5 must consist of at least three active partitions. Optionally you can have a spare disk in the array which will take the place of the failed disk in the case of failure. </para><para> As you can see, RAID5 has a similar degree of reliability to RAID1 while achieving less redundancy. On the other hand, it might be a bit slower on write operations than RAID0 due to computation of parity information. </para></listitem> </varlistentry> <varlistentry> <term>RAID6</term><listitem><para> Is similar to RAID5 except that it uses two parity devices instead of one. </para><para> A RAID6 array can survive up to two disk failures. </para></listitem> </varlistentry> <varlistentry> <term>RAID10</term><listitem><para> RAID10 combines striping (as in RAID0) and mirroring (as in RAID1). It creates <replaceable>n</replaceable> copies of incoming data and distributes them across the partitions so that none of the copies of the same data are on the same device. The default value of <replaceable>n</replaceable> is 2, but it can be set to something else in expert mode. The number of partitions used must be at least <replaceable>n</replaceable>. RAID10 has different layouts for distributing the copies. The default is near copies. Near copies have all of the copies at about the same offset on all of the disks. Far copies have the copies at different offsets on the disks. Offset copies copy the stripe, not the individual copies. </para><para> RAID10 can be used to achieve reliability and redundancy without the drawback of having to calculate parity. </para></listitem> </varlistentry> </variablelist> To sum it up:
