Once you have gathered information about your computer's hardware,
|
| 9 |
check that your hardware will let you do the type of installation
|
| 10 |
that you want to do.

Depending on your needs, you might manage with less than some of the
|
| 15 |
recommended hardware listed in the table below. However, most users
|
| 16 |
risk being frustrated if they ignore these suggestions.

A Pentium 4, 1GHz system is the minimum recommended for a desktop

The actual minimum memory requirements are a lot less then the numbers
|
| 59 |
listed in this table. Depending on the architecture, it is possible to
|
| 60 |
install Debian with as little as 20MB (for s390) to 48MB (for i386 and
|
| 61 |
amd64). The same goes for the disk space requirements, especially if you
|
| 62 |
pick and choose which applications to install; see
|
| 63 |
<xref linkend="tasksel-size-list"/> for additional information on disk
|
| 64 |
space requirements.

It is possible to run a graphical desktop environment on older or
|
| 69 |
low-end systems, but in that case it is recommended to install
|
| 70 |
a window manager that is less resource-hungry than those of the
|
| 71 |
GNOME or KDE desktop environments; alternatives include
|
| 72 |
<classname>xfce4</classname>, <classname>icewm</classname> and
|
| 73 |
<classname>wmaker</classname>, but there are others to choose from.

It is practically impossible to give general memory or disk space
|
| 78 |
requirements for server installations as those very much depend on
|
| 79 |
what the server is to be used for.

Remember that these sizes don't include all the other materials which
|
| 84 |
are usually to be found, such as user files, mail, and data. It is
|
| 85 |
always best to be generous when considering the space for your own
|
| 86 |
files and data.

Disk space required for the smooth operation of the &debian; system
|
| 91 |
itself is taken into account in these recommended system requirements.
|
| 92 |
Notably, the <filename>/var</filename> partition contains
|
| 93 |
a lot of state information specific to Debian in addition to its regular
|
| 94 |
contents, like logfiles. The
|
| 95 |
<command>dpkg</command> files (with information on all installed
|
| 96 |
packages) can easily consume 40MB. Also,
|
| 97 |
<command>apt-get</command> puts downloaded packages here before they are
|
| 98 |
installed. You should
|
| 99 |
usually allocate at least 200MB for <filename>/var</filename>, and a lot
|
| 100 |
more if you install a graphical desktop environment.
