If mod_rewrite is not enabled, the URL handling will not work properly (specifically the mapping of the URLs TYPO3 uses internally for "speaking URLs") and you might receive 404 (page not found) errors.
How Apache modules are enabled, depends on your system. Check the documentation for your operating system distribution.
