Du skal have mindst 485MB hukommelse og 920MB harddiskplads for at udføre en normal installation. Bemærk at dette er omtrentlige minimumstal. For mere realistiske tal, se Afsnit 3.4, “Opfyldelse af udstyrets minimumskrav”.
The installer normally automatically enables memory-saving tricks to be able to run on such low-memory system, but on architectures that are less tested it may miss doing so. It can however be enabled manually by appending the
lowmem=1 or even
lowmem=2 boot parameter (see also Afsnit 126.96.36.199, “Kontroller tilgænglig hukommelse / tilstand for lav hukommelse” and Afsnit 5.3.2, “Parametre for Debian-installationsprogrammet”).
Installation on systems with less memory or disk space available may be possible but is only advised for experienced users.
 Installation images that support the graphical installer require more memory than images that support only the text-based installer and should not be used on systems with less than 485MB of memory. If there is a choice between booting the text-based and the graphical installer, the former should be selected on such systems.
