It doesn't know much about your hardware, preferred language, or even the task it should perform. Don't worry. Because &d-i; is quite clever, it can automatically probe your hardware, locate the rest of its components and upgrade itself to a capable installation system. However, you still need to help &d-i; with some information it can't determine automatically (like selecting your preferred language, keyboard layout or desired network mirror)."

470
488
msgid "If that is not sufficient, the installer will further reduce memory consumption by loading only those components essential to complete a basic installation. This reduces the functionality of the installation system. You will be given the opportunity to load additional components manually, but you should be aware that each component you select will use additional memory and thus may cause the installation to fail."
476
494
msgid "If the installer runs in low memory mode, it is recommended to create a relatively large swap partition (64–128MB). The swap partition will be used as virtual memory and thus increases the amount of memory available to the system. The installer will activate the swap partition as early as possible in the installation process. Note that heavy use of swap will reduce performance of your system and may lead to high disk activity."
482
500
msgid "Despite these measures, it is still possible that your system freezes, that unexpected errors occur or that processes are killed by the kernel because the system runs out of memory (which will result in <quote>Out of memory</quote> messages on VT4 and in the syslog)."

msgid "For example, it has been reported that creating a big ext3 file system fails in low memory mode when there is insufficient swap space.

584
602
msgid "At first, <command>iso-scan</command> automatically mounts all block devices (e.g. partitions) which have some known filesystem on them and sequentially searches for filenames ending with <filename>.iso</filename> (or <filename>.ISO</filename> for that matter). Beware that the first attempt scans only files in the root directory and in the first level of subdirectories (i.e. it finds <filename>/<replaceable>whatever</replaceable>.iso</filename>, <filename>/data/<replaceable>whatever</replaceable>.iso</filename>, but not <filename>/data/tmp/<replaceable>whatever</replaceable>.iso</filename>). After an iso image has been found, <command>iso-scan</command> checks its content to determine if the image is a valid Debian iso image or not. In the former case we are done, in the latter <command>iso-scan</command> seeks for another image."
590
608
msgid "In case the previous attempt to find an installer iso image fails, <command>iso-scan</command> will ask you whether you would like to perform a more thorough search. This pass doesn't just look into the topmost directories, but really traverses whole filesystem."

For further explanation, check the error messages on the fourth console. In any case, you will be asked if you want to retry, or if you want to perform a manual setup. DHCP servers are sometimes really slow in their responses, so if you are sure everything is in place, try again."

737

However, the installer will ask you to confirm these changes before they are written to disk."
