1 There are two menu systems included with SYSLINUX, the advanced menu
2 system, and the simple menu system.
5 +++ THE ADVANCED MENU SYSTEM +++
7 The advanced menu system, written by Murali Krishnan Ganapathy, is
8 located in the menu/ subdirectly. It allows the user to create
9 hierarchial submenus, dynamic options, checkboxes, and just about
10 anything you want. It requires that the menu is compiled from a
11 simple C file, see menu/simple.c and menu/complex.c for examples.
13 The advanced menu system doesn't support serial console at this time.
15 See menu/README for more information.
18 +++ THE SIMPLE MENU SYSTEM +++
20 The simple menu system is a single module located at
21 com32/modules/vesamenu.c32 (graphical) or com32/modules/menu.c32 (text
22 mode only). It uses the same configuration file as the regular
23 SYSLINUX command line, and displays all the LABEL statements.
25 To use the menu system, simply make sure [vesa]menu.c32 is in the
26 appropriate location for your boot medium (the same directory as the
27 configuration file for SYSLINUX, EXTLINUX and ISOLINUX, and the same
28 directory as pxelinux.0 for PXELINUX), and put the following options
29 in your configuration file:
35 There are a few menu additions to the command line, all starting with
36 the keywords MENU or TEXT; like the rest of the SYSLINUX config file
37 language, it is case insensitive:
41 Give the menu a title. The title is presented at the top of
46 Do not display the actual menu unless the user presses a key.
47 All that is displayed is a timeout message.
51 Insert an empty line in the menu.
55 (Only valid after a LABEL statement.)
56 Changes the label displayed for a specific entry. This allows
57 you to have a label that isn't suitable for the command line,
62 MENU LABEL Soft Cap ^Linux 9.6.36
63 KERNEL softcap-9.6.36.bzi
66 # A very dense operating system
68 MENU LABEL ^Windows CE/ME/NT
72 The ^ symbol in a MENU LABEL statement defines a hotkey.
73 The hotkey will be highlighted in the menu and will move the
74 menu cursor immediately to that entry.
76 Reusing hotkeys is disallowed, subsequent entries will not be
77 highlighted, and will not work.
79 Keep in mind that the LABELs, not MENU LABELs, must be unique,
80 or odd things will happen to the command-line.
85 (Only valid after a LABEL statement.)
86 Will add "count" spaces in front of the displayed menu entry.
90 (Only valid after a LABEL statement.)
91 Makes the entry unselectable. This allows you to make a
92 section in your menu with different options below it.
95 # Entries for network boots
102 MENU LABEL Soft Cap ^Linux 9.6.36
104 KERNEL softcap-9.6.36.bzi
112 APPEND initrd=dos622.imz
117 # Entries for local boots
124 MENU LABEL ^Windows 2000
131 MENU LABEL Windows ^XP
138 (Only valid after a LABEL statement.)
139 Suppresses a particular LABEL entry from the menu.
144 (Only valid after a LABEL statement.)
145 Indicates that this entry should be the default. If no
146 default is specified, use the first one.
151 ... which can span multiple lines
154 (Only valid after a LABEL statement.)
156 Specifies a help text that should be displayed when a particular
157 selection is highlighted.
162 (Only valid after a LABEL statement.)
164 Sets a password on this menu entry. "passwd" can be either a
165 cleartext password, a SHA-1 encrypted password (starting with
166 $4$), or and MD5 encrypted password (starting with $1$).
168 Use the included Perl scripts "sha1pass" or "md5pass" to
169 encrypt passwords. MD5 passwords are compatible with most
170 Unix password file utilities; SHA-1 passwords are probably
171 unique to SYSLINUX. Obviously, if you don't encrypt your
172 passwords they will not be very secure at all.
174 If you are using passwords, you want to make sure you also use
175 the settings "NOESCAPE 1", "PROMPT 0", and either set
176 "ALLOWOPTIONS 0" or use a master password (see below.)
178 If passwd is an empty string, this menu entry can only be
179 unlocked with the master password.
182 MENU MASTER PASSWD passwd
184 Sets a master password. This password can be used to boot any
185 menu entry, and is required for the [Tab] and [Esc] keys to
189 MENU BACKGROUND background
191 For vesamenu.c32, sets the background image. The background
192 can either be a color (see MENU COLOR) or the name of an image
193 file, which should be 640x480 pixels and either in PNG or JPEG
200 Begin/end a submenu. The entries between MENU BEGIN and MENU
201 END form a submenu, which is marked with a > mark on the right
202 hand of the screen. Submenus inherit the properties of their
203 parent menus, but can override them, and can thus have their
204 own backgrounds, master passwords, titles, timeouts, messages
210 (Only valid after a LABEL statement.)
212 This label will transfer to the named submenu instead of
213 booting anything. To transfer to the top-level menu, specify
219 (Only valid after a LABEL statement.)
221 This label quits the menu system.
223 WARNING: if MENU MASTER PASSWD or ALLOWOPTIONS 0 is set, this
224 will still allow exiting to the CLI; however, a separate MENU
225 PASSWD can of course be set for this label.
229 MENU INCLUDE filename
231 Include the contents of the configuration file filename at
234 In the case of MENU INCLUDE, the included data is only seen by
235 the menu system; the core syslinux code does not parse this
236 command, so any labels defined in it are unavailable.
239 MENU AUTOBOOT message
241 Replaces the message "Automatic boot in # second{,s}...". The
242 symbol # is replaced with the number of seconds remaining.
243 The syntax "{singular,[dual,]plural}" can be used to conjugate
249 Replaces the message "Press [Tab] to edit options".
252 MENU NOTABMSG message
254 Takes the place of the TABMSG message if option editing is
255 disabled. Defaults to blank.
258 MENU PASSPROMPT message
260 Replaces the message "Password required".
263 MENU COLOR element ansi foreground background shadow
265 Sets the color of element "element" to the specified color
268 screen Rest of the screen
271 unsel Unselected menu item
272 hotkey Unselected hotkey
274 hotsel Selected hotkey
275 disabled Disabled menu item
277 tabmsg Press [Tab] message
278 cmdmark Command line marker
280 pwdborder Password box border
281 pwdheader Password box header
282 pwdentry Password box contents
283 timeout_msg Timeout message
284 timeout Timeout counter
286 msgXX Message (F-key) file attribute XX
288 ... where XX is two hexadecimal digits (the "plain text" is 07).
290 "ansi" is a sequence of semicolon-separated ECMA-48 Set
291 Graphics Rendition (<ESC>[m) sequences:
293 0 reset all attributes to their defaults
295 4 set underscore (simulated with color on a color display)
298 22 set normal intensity
302 30 set black foreground
303 31 set red foreground
304 32 set green foreground
305 33 set brown foreground
306 34 set blue foreground
307 35 set magenta foreground
308 36 set cyan foreground
309 37 set white foreground
310 38 set underscore on, set default foreground color
311 39 set underscore off, set default foreground color
312 40 set black background
313 41 set red background
314 42 set green background
315 43 set brown background
316 44 set blue background
317 45 set magenta background
318 46 set cyan background
319 47 set white background
320 49 set default background color
322 These are used (a) in text mode, and (b) on the serial
325 "foreground" and "background" are color codes in #AARRGGBB
326 notation, where AA RR GG BB are hexadecimal digits for alpha
327 (opacity), red, green and blue, respectively. #00000000
328 represents fully transparent, and #ffffffff represents opaque
331 "shadow" controls the handling of the graphical console text
332 shadow. Permitted values are "none" (no shadowing), "std" or
333 "standard" (standard shadowing - foreground pixels are
334 raised), "all" (both background and foreground raised), and
335 "rev" or "reverse" (background pixels are raised.)
337 If any field is set to "*" or omitted (at the end of the line)
338 then that field is left unchanged.
341 The current defaults are:
343 menu color screen 37;40 #80ffffff #00000000 std
344 menu color border 30;44 #40000000 #00000000 std
345 menu color title 1;36;44 #c00090f0 #00000000 std
346 menu color unsel 37;44 #90ffffff #00000000 std
347 menu color hotkey 1;37;44 #ffffffff #00000000 std
348 menu color sel 7;37;40 #e0000000 #20ff8000 all
349 menu color hotsel 1;7;37;40 #e0400000 #20ff8000 all
350 menu color disabled 1;30;44 #60cccccc #00000000 std
351 menu color scrollbar 30;44 #40000000 #00000000 std
352 menu color tabmsg 31;40 #90ffff00 #00000000 std
353 menu color cmdmark 1;36;40 #c000ffff #00000000 std
354 menu color cmdline 37;40 #c0ffffff #00000000 std
355 menu color pwdborder 30;47 #80ffffff #20ffffff std
356 menu color pwdheader 31;47 #80ff8080 #20ffffff std
357 menu color pwdentry 30;47 #80ffffff #20ffffff std
358 menu color timeout_msg 37;40 #80ffffff #00000000 std
359 menu color timeout 1;37;40 #c0ffffff #00000000 std
360 menu color help 37;40 #c0ffffff #00000000 std
361 menu color msg07 37;40 #90ffffff #00000000 std
364 MENU MSGCOLOR fg_filter bg_filter shadow
366 Sets *all* the msgXX colors to a color scheme derived from the
367 fg_filter and bg_filter values. Background color zero is
368 always treated as transparent. The default corresponds to:
370 menu msgcolor #90ffffff #80ffffff std
372 This directive should come before any directive that
373 customizes individual msgXX colors.
378 MENU PASSWORDMARGIN 3
386 MENU HELPMSGENDROW -1
391 These options control the layout of the menu on the screen.
392 The values above are the defaults.
394 A negative value is relative to the calculated length of the
395 screen (25 for text mode, 28 for VESA graphics mode.)
398 F1 textfile background
400 F12 textfile background
402 Displays full-screen help (also available at the command line.)
403 The same control code sequences as in the command line
404 interface are supported, although some are ignored.
406 Additionally, a second argument allows a different background
407 image (see MENU BACKGROUND for supported formats) to be displayed.
410 The menu system honours the TIMEOUT command; if TIMEOUT is specified
411 it will execute the ONTIMEOUT command if one exists, otherwise it will
412 pick the default menu option.
414 Normally, the user can press [Tab] to edit the menu entry, and [Esc]
415 to return to the SYSLINUX command line. However, if the configuration
416 file specifies ALLOWOPTIONS 0, these keys will be disabled, and if
417 MENU MASTER PASSWD is set, they require the master password.
419 The simple menu system supports serial console, using the normal
420 SERIAL directive. However, it can be quite slow over a slow serial
421 link; you probably want to set your baudrate to 38400 or higher if
422 possible. It requires a Linux/VT220/ANSI-compatible terminal on the
426 +++ USING AN ALTERNATE CONFIGURATION FILE +++
429 It is also possible to load a secondary configuration file, to get to
430 another menu. To do that, invoke menu.c32 with the name of the
431 secondary configuration file.
434 MENU LABEL Another Menu
436 APPEND othermenu.conf
438 If you specify more than one file, they will all be read, in the order
439 specified. The dummy filename ~ (tilde) is replaced with the filename
440 of the main configuration file.
442 # The file graphics.conf contains common color and layout commands for
445 MENU LABEL Another Menu
447 APPEND graphics.conf othermenu.conf
449 # Return to the main menu
451 MENU LABEL Return to Main Menu
453 APPEND graphics.conf ~
455 See also the MENU INCLUDE directive above.
