BRAND.4TH(8)						    BSD System Manager's Manual 					      BRAND.4TH(8)

NAME
brand.4th -- FreeBSD ASCII art boot module DESCRIPTION
The file that goes by the name of brand.4th is a set of commands designed to draw the ASCII art BSD brand above the boot loader menu. The commands of brand.4th by themselves are not enough for most uses. Please refer to the examples below for the most common situations, and to loader(8) for additional commands. Before using any of the commands provided in brand.4th, it must be included through the command: include brand.4th This line is present in the default /boot/menu.rc file, so it is not needed (and should not be re-issued) in a normal setup. The commands provided by it are: draw-brand Draws the BSD brand. The brand that is drawn is configured by setting the loader_brand variable in loader.conf(5) to one of ``fbsd'' (the default) or ``none''. The position of the logo can be configured by setting the loader_brand_x and loader_brand_y variables in loader.conf(5). The default values are 2 (x) and 1 (y). The environment variables that effect its behavior are: loader_brand Selects the desired brand in the beastie boot menu. Possible values are: ``fbsd'' (default) or ``none''. loader_brand_x Sets the desired column position of the brand. Default is 2. loader_brand_y Sets the desired row position of the brand. Default is 1. FILES

MENU.4TH(8)						    BSD System Manager's Manual 					       MENU.4TH(8)

NAME
menu.4th -- FreeBSD dynamic menu boot module DESCRIPTION
The file that goes by the name of menu.4th is a set of commands designed to display a dynamic menu system managed through a system of care- fully named environment variables. The commands of menu.4th by themselves are not enough for most uses. Please refer to the examples below for the most common situations, and to loader(8) for additional commands. Before using any of the commands provided in menu.4th, it must be included through the command: include menu.4th This line is present in the default /boot/menu.rc file, so it is not needed (and should not be re-issued) in a normal setup. The commands provided by it are: menu-init Draws the menu bounding box and initializes some internal state variables. This should be called before any other menu-related functions. menu-display Displays the menu (configured via the below documented environment variables) and blocks on keyboard input, awaiting user action. menu-erase Clears the screen area within the menu bounding box. menu-redraw Calls menu-erase and then redraws the menu. menu-unset Unsets the environment variables associated with individual menu items, clearing the way for a new menu. menu-clear Calls menu-unset and then menu-erase. The environment variables that effect its behavior are: loader_color If set to ``NO'' (case-insensitive) or ``0'', causes the menu to be displayed without color. The default is to use ANSI col- oring whenever possible. If serial boot is enabled, color is disabled by default. Color features include the use of ANSI bold for numbers appearing to the left of menuitems and the use of special ``ansi'' variables described below. autoboot_delay Number of seconds menu-display will wait before executing menu_timeout_command (boot by default) unless a key is pressed. If set to ``NO'' (case-insensitive) menu-display will wait for user input and never execute menu_timeout_command. If set to ``-1'', menu-display will boot immediately, preventing both interruption of the autoboot process and escaping to the loader prompt. Default is ``10''. See loader(8) for additional information. menu_timeout_command The command to be executed after autoboot_delay seconds if a key is not pressed. The default is boot. loader_menu_frame Sets the desired box style to draw around the boot menu. Possible values are: ``single'' (the default), ``double'', and ``none''. loader_menu_timeout_x Sets the desired column position of the timeout countdown text. Default is 4. loader_menu_timeout_y Sets the desired row position of the timeout countdown text. Default is 23. loader_menu_title The text to display above the menu. Default is ``Welcome to FreeBSD''. loader_menu_title_align Default is to align loader_menu_title centered above the menu. This can be set to ``left'' or ``right'' to instead display the title left-or-right justified (respectively). loader_menu_x Sets the desired column position of the boot menu. Default is 5. loader_menu_y Sets the desired row position of the boot menu. Default is 10. menu_caption[x] The text to be displayed for the numbered menuitem ``x''. menu_command[x] The command to be executed when the number associated with menuitem ``x'' is pressed. See the list of included FICL words below for some ideas. menu_keycode[x] An optional decimal ASCII keycode to be associated with menuitem ``x''. When pressed, will cause the execution of menu_command[x]. ansi_caption[x] If loader_color is set (enabled by default), use this caption for menuitem ``x'' instead of menu_caption[x]. toggled_text[x] For menuitems where menu_command[x] is set to ``toggle_menuitem'' (or a derivative thereof), the text displayed will toggle between this and menu_caption[x]. toggled_ansi[x] Like toggled_text[x] except used when loader_color is enabled (default). menu_caption[x][y] For menuitems where menu_command[x] is set to ``cycle_menuitem'' (or a derivative thereof), the text displayed will cycle between this and other menu_caption[x][y] entries. ansi_caption[x][y] Like menu_caption[x][y] except used when loader_color is enabled (default). menu_acpi When set to a number ``x'' associated with a given menuitem, that menuitem will only appear when running on i386-compatible hardware, hint.acpi.0.rsdp is set (indicating the presence of hardware ACPI support as detected by loader(8)), and hint.acpi.0.disabled is not set. On non-i386 hardware, menuitems configured after the ``menu_acpi'' menuitem will use a lower number (to compensate for the missing ACPI menuitem) but continue to function as expected. On i386-compatible hardware lacking ACPI support (as detected by loader(8)), subsequent menuitems will retain their associated numbers. hint.acpi.0.rsdp Set automatically by loader(8) on i386-compatible hardware when ACPI support is detected at boot time. Effects the display of the ``menu_acpi'' menuitem (if configured). hint.acpi.0.disabled Effects the display of the menu_acpi menuitem. If set, the menuitem will display toggled_text[x] (toggled_ansi[x] if loader_color is set), otherwise menu_caption[x] (ansi_caption[x] if loader_color is set). menu_options When set to a number ``x'', a single blank-line and an ``Options'' header are inserted between menu_caption[x-1] and menu_caption[x] (if configured). menu_reboot If set, adds a built-in ``Reboot'' menuitem to the end of the last configured menuitem. If menu_options is configured, the ``Reboot'' menuitem will be inserted before the ``Options'' separator. In addition, it provides the following FICL words: arch-i386? (-- BOOL) Returns true (-1) on i386 and false (0) otherwise. acpipresent? (-- BOOL) Returns true (-1) if ACPI is present and false (0) otherwise. acpienabled? (-- BOOL) Returns true (-1) if ACPI is enabled and false (0) otherwise. toggle_menuitem (N -- N) Toggles menuitem ``N'' between menu_caption[x] and toggled_text[x] (where ``N'' represents the ASCII decimal value for ``x''). cycle_menuitem (N -- N) Cycles menuitem ``N'' between menu_caption[x][y] entries (where N represents the ASCII decimal value for x). For all values of ``x'' above, use any number between 1 through 9. Sorry, double-digits are not currently supported. FILES
