It allows the user to create +hierarchial submenus, dynamic options, checkboxes, and just about +anything you want. It requires that the menu is compiled from a +simple C file, see menu/simple.c and menu/complex.c for examples. + +The advanced menu system doesn't support serial console at this time. + +See menu/README for more information. + + ++++ THE SIMPLE MENU SYSTEM +++ + +The simple menu system is a single module located at +com32/modules/vesamenu.c32 (graphical) or com32/modules/menu.c32 (text +mode only). It uses the same configuration file as the regular +SYSLINUX command line, and displays all the LABEL statements. + +To use the menu system, simply make sure [vesa]menu.c32 is in the +appropriate location for your boot medium (the same directory as the +configuration file for SYSLINUX, EXTLINUX and ISOLINUX, and the same +directory as pxelinux.0 for PXELINUX), and put the following options +in your configuration file: + +DEFAULT menu.c32 +PROMPT 0 + + +There are a few menu additions to the command line, all starting with +the keywords MENU or TEXT; like the rest of the SYSLINUX config file +language, it is case insensitive: + +MENU TITLE title + + Give the menu a title. The title is presented at the top of + the menu. + +MENU HIDDEN + + Do not display the actual menu unless the user presses a key. + All that is displayed is a timeout message. + +MENU SEPARATOR + + Insert an empty line in the menu. + +MENU LABEL label + + (Only valid after a LABEL statement.) + Changes the label displayed for a specific entry. This allows + you to have a label that isn't suitable for the command line, + for example: + + # Soft Cap Linux + LABEL softcap + MENU LABEL Soft Cap ^Linux 9.6.36 + KERNEL softcap-9.6.36.bzi + APPEND whatever + + # A very dense operating system + LABEL brick + MENU LABEL ^Windows CE/ME/NT + KERNEL chain.c32 + APPEND hd0 2 + + The ^ symbol in a MENU LABEL statement defines a hotkey. + The hotkey will be highlighted in the menu and will move the + menu cursor immediately to that entry. + + Reusing hotkeys is disallowed, subsequent entries will not be + highlighted, and will not work. + + Keep in mind that the LABELs, not MENU LABELs, must be unique, + or odd things will happen to the command-line. + + +MENU INDENT count + + (Only valid after a LABEL statement.) + Will add "count" spaces in front of the displayed menu entry. + +MENU DISABLE + + (Only valid after a LABEL statement.) + Makes the entry unselectable. This allows you to make a + section in your menu with different options below it. + for example: + + # Entries for network boots + LABEL + MENU LABEL Network: + MENU DISABLE + + # Soft Cap Linux + LABEL softcap + MENU LABEL Soft Cap ^Linux 9.6.36 + MENU INDENT 1 + KERNEL softcap-9.6.36.bzi + APPEND whatever + + # Dos 6.22 + LABEL dos + MENU LABEL ^Dos 6.22 + MENU INDENT 1 + KERNEL memdisk + APPEND initrd=dos622.imz + + # Separator + MENU SEPARATOR + + # Entries for local boots + LABEL + MENU LABEL Local: + MENU DISABLE + + # Windows 2000 + LABEL w2k + MENU LABEL ^Windows 2000 + MENU INDENT 1 + KERNEL chain.c32 + APPEND hd0 1 + + # Windows XP + LABEL xp + MENU LABEL Windows ^XP + MENU INDENT 1 + KERNEL chain.c32 + APPEND hd0 2 + +MENU HIDE + + (Only valid after a LABEL statement.) + Suppresses a particular LABEL entry from the menu. + + +MENU DEFAULT + + (Only valid after a LABEL statement.) + Indicates that this entry should be the default. If no + default is specified, use the first one. + + +TEXT HELP +Help text ... +... which can span multiple lines +ENDTEXT + + (Only valid after a LABEL statement.) + Specifies a help text that should be displayed when a particular + selection is highlighted. + + +MENU PASSWD passwd + + (Only valid after a LABEL statement.) + + Sets a password on this menu entry. "passwd" can be either a + cleartext password, a SHA-1 encrypted password (starting with + $4$), or and MD5 encrypted password (starting with $1$). + + Use the included Perl scripts "sha1pass" or "md5pass" to + encrypt passwords. MD5 passwords are compatible with most + Unix password file utilities; SHA-1 passwords are probably + unique to SYSLINUX. Obviously, if you don't encrypt your + passwords they will not be very secure at all. + + If you are using passwords, you want to make sure you also use + the settings "NOESCAPE 1", "PROMPT 0", and either set + "ALLOWOPTIONS 0" or use a master password (see below.) + + If passwd is an empty string, this menu entry can only be + unlocked with the master password. + + +MENU MASTER PASSWD passwd + + Sets a master password. This password can be used to boot any + menu entry, and is required for the [Tab] and [Esc] keys to + work. + + +MENU BACKGROUND background + + For vesamenu.c32, sets the background image. The background + can either be a color (see MENU COLOR) or the name of an image + file, which should be 640x480 pixels and either in PNG or JPEG + format. + + +INCLUDE filename +MENU INCLUDE filename + + Include the contents of the configuration file filename at + this point. + + In the case of MENU INCLUDE, the included data is only seen by + the menu system; the core syslinux code does not parse this + command, so any labels defined in it are unavailable. + + +MENU AUTOBOOT message + + Replaces the message "Automatic boot in # second{,s}...". The + symbol # is replaced with the number of seconds remaining. + The syntax "{singular,[dual,]plural}" can be used to conjugate + appropriately. + + +MENU TABMSG message + + Replaces the message "Press [Tab] to edit options". + + +MENU NOTABMSG message + + Takes the place of the TABMSG message if option editing is + disabled.

However, if the configuration +file specifies ALLOWOPTIONS 0, these keys will be disabled, and if +MENU MASTER PASSWD is set, they require the master password. + +The simple menu system supports serial console, using the normal +SERIAL directive.
