31 | "Some kernel features may be built directly into the kernel.\n" | |
32 | "Some may be made into loadable runtime modules. Some features\n" | |
33 | "may be completely removed altogether. There are also certain\n" | |
34 | "kernel parameters which are not really features, but must be\n" | |
35 | "entered in as decimal or hexadecimal numbers or possibly text.\n" | |
36 | "\n" | |
37 | "Menu items beginning with [*], <M> or [ ] represent features\n" | |
38 | "configured to be built in, modularized or removed respectively.\n" | |
39 | "Pointed brackets <> represent module capable features.\n" | |
40 | "\n" | |

63 | "\n" | |
64 | " Shortcut: Press <ESC><ESC> or <E> or <X> if there is no hotkey\n" | |

66 | " there is a delayed response which you may find annoying.\n" | |

114 | "-----------------------------\n" | |

117 | "between different kernel configurations.\n" | |
118 | "\n" | |
119 | "At the end of the main menu you will find two options. One is\n" | |
120 | "for saving the current configuration to a file of your choosing.\n" | |
121 | "The other option is for loading a previously saved alternate\n" | |
122 | "configuration.\n" | |
123 | "\n" | |
124 | "Even if you don't use alternate configuration files, but you\n" | |
125 | "find during a Menuconfig session that you have completely messed\n" | |
126 | "up your settings, you may use the \"Load Alternate...\" option to\n" | |
127 | "restore your previously saved settings from \".config\" without\n" | |
128 | "restarting Menuconfig.\n" | |
129 | "\n" | |
130 | "Other information\n" | |
131 | "-----------------\n" | |
132 | "If you use Menuconfig in an XTERM window make sure you have your\n" | |
133 | "$TERM variable set to point to a xterm definition which supports color.\n" | |
134 | "Otherwise, Menuconfig will look rather bad. Menuconfig will not\n" | |
135 | "display correctly in a RXVT window because rxvt displays only one\n" | |
136 | "intensity of color, bright.\n" | |
137 | "\n" | |
138 | "Menuconfig will display larger menus on screens or xterms which are\n" | |
139 | "set to display more than the standard 25 row by 80 column geometry.\n" | |
140 | "In order for this to work, the \"stty size\" command must be able to\n" | |
141 | "display the screen's current row and column geometry. I STRONGLY\n" | |
142 | "RECOMMEND that you make sure you do NOT have the shell variables\n" | |
143 | "LINES and COLUMNS exported into your environment. Some distributions\n" | |
144 | "export those variables via /etc/profile. Some ncurses programs can\n" | |
