Du skal have mindst 780MB 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 6.3.1.1, “Kontroller tilgænglig hukommelse / tilstand for lav hukommelse” and Afsnit 5.3.2, “Parametre for Debian-installationsprogrammet”).

Installation on systems with less memory^[2] or disk space available may be possible but is only advised for experienced users.
