You must have at least &minimum-memory; of memory and &minimum-fs-size; of hard disk space to perform a normal installation. Note that these are fairly minimal numbers. For more realistic figures, see . 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 and ). On &architecture; the lowmem levels have not been tested, so automatic detection is probably outdated and you thus probably need to pass the boot parameter if your system has little memory. Installation on systems with less memory 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 &minimum-memory; of memory. If there is a choice between booting the text-based and the graphical installer, the former should be selected on such systems. or disk space available may be possible but is only advised for experienced users.
