- Menuconfig gives the Linux kernel configuration a long needed face
- lift. Featuring text based color menus and dialogs, it does not
- require X Windows. With this utility you can easily select a kernel
- option to modify without sifting through 100 other options.
- Overview
- --------
- Some kernel features may be built directly into the kernel.
- Some may be made into loadable runtime modules. Some features
- may be completely removed altogether. There are also certain
- kernel parameters which are not really features, but must be
- entered in as decimal or hexadecimal numbers or possibly text.
- Menu items beginning with [*], <M> or [ ] represent features
- configured to be built in, modularized or removed respectively.
- Pointed brackets <> represent module capable features.
- more...
- To change any of these features, highlight it with the cursor
- keys and press <Y> to build it in, <M> to make it a module or
- <N> to removed it. You may also press the <Space Bar> to cycle
- through the available options (ie. Y->N->M->Y).
- Items beginning with numbers or other text within parenthesis can
- be changed by highlighting the item and pressing <Enter>. Then
- enter the new parameter into the dialog box that pops up.
- Some additional keyboard hints:
- Menus
- ----------
- o Use the Up/Down arrow keys (cursor keys) to highlight the item
- you wish to change or submenu wish to select and press <Enter>.
- Submenus are designated by "--->".
- Shortcut: Press the option's highlighted letter (hotkey).
- Pressing a hotkey more than once will sequence
- through all visible items which use that hotkey.
- You may also use the <PAGE UP> and <PAGE DOWN> keys to scroll
- unseen options into view.
- o To exit a menu use the cursor keys to highlight the <Exit> button
- and press <ENTER>.
- Shortcut: Press <ESC><ESC> or <E> or <X> if there is no hotkey
- using those letters. You may press a single <ESC>, but
- there is a delayed response which you may find annoying.
- Also, the <TAB> and cursor keys will cycle between <Select>,
- <Exit> and <Help>
- o To get help with an item, use the cursor keys to highlight <Help>
- and Press <ENTER>.
- Shortcut: Press <H> or <?>.
- Radiolists (Choice lists)
- -----------
- o Use the cursor keys to select the option you wish to set and press
- <S> or the <SPACE BAR>.
- Shortcut: Press the first letter of the option you wish to set then
- press <S> or <SPACE BAR>.
- o To see available help for the item, use the cursor keys to highlight
- <Help> and Press <ENTER>.
- Shortcut: Press <H> or <?>.
- Also, the <TAB> and cursor keys will cycle between <Select> and
- <Help>
- Data Entry
- -----------
- o Enter the requested information and press <ENTER>
- If you are entering hexadecimal values, it is not necessary to
- add the '0x' prefix to the entry.
- o For help, use the <TAB> or cursor keys to highlight the help option
- and press <ENTER>. You can try <TAB><H> as well.
- Text Box (Help Window)
- --------
- o Use the cursor keys to scroll up/down/left/right. The VI editor
- keys h,j,k,l function here as do <SPACE BAR> and <B> for those
- who are familiar with less and lynx.
- o Press <E>, <X>, <Enter> or <Esc><Esc> to exit.
- Final Acceptance
- ----------------
- With the exception of the old style sound configuration,
- YOUR CHANGES ARE NOT FINAL. You will be given a last chance to
- confirm them prior to exiting Menuconfig.
- If Menuconfig quits with an error while saving your configuration,
- you may look in the file /usr/src/linux/.menuconfig.log for
- information which may help you determine the cause.
- Alternate Configuration Files
- -----------------------------
- Menuconfig supports the use of alternate configuration files for
- those who, for various reasons, find it necessary to switch
- between different kernel configurations.
- At the end of the main menu you will find two options. One is
- for saving the current configuration to a file of your choosing.
- The other option is for loading a previously saved alternate
- configuration.
- Even if you don't use alternate configuration files, but you
- find during a Menuconfig session that you have completely messed
- up your settings, you may use the "Load Alternate..." option to
- restore your previously saved settings from ".config" without
- restarting Menuconfig.
- Other information
- -----------------
- The windowing utility, lxdialog, will only be rebuilt if your kernel
- source tree is fresh, or changes are patched into it via a kernel
- patch or you do 'make mrproper'. If changes to lxdialog are patched
- in, most likely the rebuild time will be short. You may force a
- complete rebuild of lxdialog by changing to it's directory and doing
- 'make clean all'
- If you use Menuconfig in an XTERM window make sure you have your
- $TERM variable set to point to a xterm definition which supports color.
- Otherwise, Menuconfig will look rather bad. Menuconfig will not
- display correctly in a RXVT window because rxvt displays only one
- intensity of color, bright.
- Menuconfig will display larger menus on screens or xterms which are
- set to display more than the standard 25 row by 80 column geometry.
- In order for this to work, the "stty size" command must be able to
- display the screen's current row and column geometry. I STRONGLY
- RECOMMEND that you make sure you do NOT have the shell variables
- LINES and COLUMNS exported into your environment. Some distributions
- export those variables via /etc/profile. Some ncurses programs can
- become confused when those variables (LINES & COLUMNS) don't reflect
- the true screen size.
- NOTICE: lxdialog requires the ncurses libraries to compile. If you
- don't already have ncurses you really should get it.
- The makefile for lxdialog attempts to find your ncurses
- header file. Although it should find the header for older
- versions of ncurses, it is probably a good idea to get the
- latest ncurses anyway.
- If you have upgraded your ncurses libraries, MAKE SURE you
- remove the old ncurses header files. If you don't you
- will most certainly get a segmentation fault.
- WARNING: It is not recommended that you change any defines in
- lxdialog's header files. If you have a grayscale display and
- are brave, you may tinker with color.h to tune the colors to
- your preference.
- COMPATIBILITY ISSUE:
- There have been some compatibility problems reported with
- older versions of bash and sed. I am trying to work these
- out but it is preferable that you upgrade those utilities.
- ******** IMPORTANT, OPTIONAL ALTERNATE PERSONALITY AVAILABLE ********
- ******** ********
- If you prefer to have all of the kernel options listed in a single
- menu, rather than the default multimenu hierarchy, you may edit the
- Menuconfig script and change the line "single_menu_mode=" to
- "single_menu_mode=TRUE".
- This mode is not recommended unless you have a fairly fast machine.

- Propaganda
- ----------
- The windowing support utility (lxdialog) is a VERY modified version of
- the dialog utility by Savio Lam <lam836@cs.cuhk.hk>. Although lxdialog
- is significantly different from dialog, I have left Savio's copyrights
- intact. Please DO NOT contact Savio with questions about lxdialog.
- He will not be able to assist.
- William Roadcap was the original author of Menuconfig.
- Michael Elizabeth Chastain <mec@shout.net> is the current maintainer.
