  1. config ISO9660_FS
  2. tristate "ISO 9660 CDROM file system support"
  3. help
  4. This is the standard file system used on CD-ROMs. It was previously
  5. known as "High Sierra File System" and is called "hsfs" on other
  6. Unix systems. The so-called Rock-Ridge extensions which allow for
  7. long Unix filenames and symbolic links are also supported by this
  8. driver. If you have a CD-ROM drive and want to do more with it than
  9. just listen to audio CDs and watch its LEDs, say Y (and read
  10. <file:Documentation/filesystems/isofs.txt> and the CD-ROM-HOWTO,
  11. available from <http://www.tldp.org/docs.html#howto>), thereby
  12. enlarging your kernel by about 27 KB; otherwise say N.
  13. To compile this file system support as a module, choose M here: the
  14. module will be called isofs.
  15. config JOLIET
  16. bool "Microsoft Joliet CDROM extensions"

  18. select NLS
  19. help
  20. Joliet is a Microsoft extension for the ISO 9660 CD-ROM file system
  21. which allows for long filenames in unicode format (unicode is the
  22. new 16 bit character code, successor to ASCII, which encodes the
  23. characters of almost all languages of the world; see
  24. <http://www.unicode.org/> for more information). Say Y here if you
  25. want to be able to read Joliet CD-ROMs under Linux.
  26. config ZISOFS
  27. bool "Transparent decompression extension"
  28. depends on ISO9660_FS
  29. select ZLIB_INFLATE
  30. help
  31. This is a Linux-specific extension to RockRidge which lets you store
  32. data in compressed form on a CD-ROM and have it transparently
  33. decompressed when the CD-ROM is accessed. See
  34. <http://www.kernel.org/pub/linux/utils/fs/zisofs/> for the tools
  35. necessary to create such a filesystem. Say Y here if you want to be
  36. able to read such compressed CD-ROMs.
