1.36 +"Some kernel features may be built directly into the kernel.\n"
1.37 +"Some may be made into loadable runtime modules. Some features\n"
1.38 +"may be completely removed altogether. There are also certain\n"
1.39 +"kernel parameters which are not really features, but must be\n"
1.40 +"entered in as decimal or hexadecimal numbers or possibly text.\n"
1.41 +"\n"
1.42 +"Menu items beginning with [*], <M> or [ ] represent features\n"
1.43 +"configured to be built in, modularized or removed respectively.\n"
1.44 +"Pointed brackets <> represent module capable features.\n"
1.45 +"\n"
1.46 +"To change any of these features, highlight it with the cursor\n"
1.47 +"keys and press <Y> to build it in, <M> to make it a module or\n"
1.48 +"<N> to removed it. You may also press the <Space Bar> to cycle\n"
1.49 +"through the available options (ie. Y->N->M->Y).\n"

1.51 +"Some additional keyboard hints:\n"

1.53 +"Menus\n"

1.55 +"o Use the Up/Down arrow keys (cursor keys) to highlight the item\n"
1.56 +" you wish to change or submenu wish to select and press <Enter>.\n"
1.57 +" Submenus are designated by \"--->\".\n"
1.58 +"\n"
1.59 +" Shortcut: Press the option's highlighted letter (hotkey).\n"
1.60 +" Pressing a hotkey more than once will sequence\n"
1.61 +" through all visible items which use that hotkey.\n"
1.62 +"\n"
1.63 +" You may also use the <PAGE UP> and <PAGE DOWN> keys to scroll\n"
1.64 +" unseen options into view.\n"
1.65 +"\n"
1.66 +"o To exit a menu use the cursor keys to highlight the <Exit> button\n"
1.67 +" and press <ENTER>.\n"
1.68 +"\n"
1.69 +" Shortcut: Press <ESC><ESC> or <E> or <X> if there is no hotkey\n"
1.70 +" using those letters. You may press a single <ESC>, but\n"
1.71 +" there is a delayed response which you may find annoying.\n"

1.118 +"Alternate Configuration Files\n"
1.119 +"-----------------------------\n"
1.120 +"Menuconfig supports the use of alternate configuration files for\n"
1.121 +"those who, for various reasons, find it necessary to switch\n"
1.122 +"between different kernel configurations.\n"
1.123 +"\n"
1.124 +"At the end of the main menu you will find two options. One is\n"
1.125 +"for saving the current configuration to a file of your choosing.\n"
1.126 +"The other option is for loading a previously saved alternate\n"
1.127 +"configuration.\n"
1.128 +"\n"
1.129 +"Even if you don't use alternate configuration files, but you\n"
1.130 +"find during a Menuconfig session that you have completely messed\n"
1.131 +"up your settings, you may use the \"Load Alternate...\" option to\n"
1.132 +"restore your previously saved settings from \".config\" without\n"
1.133 +"restarting Menuconfig.\n"
1.134 +"\n"
1.135 +"Other information\n"
1.136 +"-----------------\n"
1.137 +"If you use Menuconfig in an XTERM window make sure you have your\n"
1.138 +"$TERM variable set to point to a xterm definition which supports color.\n"
1.139 +"Otherwise, Menuconfig will look rather bad. Menuconfig will not\n"
1.140 +"display correctly in a RXVT window because rxvt displays only one\n"
1.141 +"intensity of color, bright.\n"
1.142 +"\n"
1.143 +"Menuconfig will display larger menus on screens or xterms which are\n"
1.144 +"set to display more than the standard 25 row by 80 column geometry.\n"
1.145 +"In order for this to work, the \"stty size\" command must be able to\n"
1.146 +"display the screen's current row and column geometry. I STRONGLY\n"
1.147 +"RECOMMEND that you make sure you do NOT have the shell variables\n"
1.148 +"LINES and COLUMNS exported into your environment. Some distributions\n"
1.149 +"export those variables via /etc/profile. Some ncurses programs can\n"
1.150 +"become confused when those variables (LINES & COLUMNS) don't reflect\n"
1.151 +"the true screen size.\n"
1.152 +"\n"
1.153 +"Optional personality available\n"
1.154 +"------------------------------\n"
1.155 +"If you prefer to have all of the kernel options listed in a single\n"
1.156 +"menu, rather than the default multimenu hierarchy, run the menuconfig\n"
1.157 +"with MENUCONFIG_MODE environment variable set to single_menu. Example:\n"
1.158 +"\n"
1.159 +"make MENUCONFIG_MODE=single_menu menuconfig\n"
1.160 +"\n"
1.161 +"<Enter> will then unroll the appropriate category, or enfold it if it\n"
1.162 +"is already unrolled.\n"
1.163 +"\n"
1.164 +"Note that this mode can eventually be a little more CPU expensive\n"
1.165 +"(especially with a larger number of unrolled categories) than the\n"
1.166 +"default mode.\n"
1.167 +"\n"
1.168 +"Different color themes available\n"
1.169 +"--------------------------------\n"
1.170 +"It is possible to select different color themes using the variable\n"
1.171 +"MENUCONFIG_COLOR. To select a theme use:\n"
1.172 +"\n"
1.173 +"make MENUCONFIG_COLOR=<theme> menuconfig\n"
1.174 +"\n"
1.175 +"Available themes are\n"
1.176 +" mono => selects colors suitable for monochrome displays\n"
1.177 +" blackbg => selects a color scheme with black background\n"
1.178 +" classic => theme with blue background. The classic look\n"
1.179 +" bluetitle => a LCD friendly version of classic. (default)\n"
