13"Overview\n"
14"--------\n"
15"Some kernel features may be built directly into the kernel.\n"
16"Some may be made into loadable runtime modules. Some features\n"
17"may be completely removed altogether. There are also certain\n"
18"kernel parameters which are not really features, but must be\n"
19"entered in as decimal or hexadecimal numbers or possibly text.\n"
20"\n"
21"Menu items beginning with following braces represent features that\n"
22" [ ] can be built in or removed\n"
23" < > can be built in, modularized or removed\n"
24" { } can be built in or modularized (selected by other feature)\n"
25" - - are selected by other feature,\n"
26" XXX cannot be selected. use Symbol Info to find out why,\n"
27"while *, M or whitespace inside braces means to build in, build as\n"
28"a module or to exclude the feature respectively.\n"
29"\n"
30"To change any of these features, highlight it with the cursor\n"
31"keys and press <Y> to build it in, <M> to make it a module or\n"
32"<N> to removed it. You may also press the <Space Bar> to cycle\n"
33"through the available options (ie. Y->N->M->Y).\n"
34"\n"
35"Some additional keyboard hints:\n"
36"\n"
37"Menus\n"
38"----------\n"
39"o Use the Up/Down arrow keys (cursor keys) to highlight the item\n"
40" you wish to change use <Enter> or <Space>. Goto submenu by \n"
41" pressing <Enter> of <right-arrow>. Use <Esc> or <left-arrow> to go back.\n"
42" Submenus are designated by \"--->\".\n"
43"\n"
44" Shortcut: Press the option's highlighted letter (hotkey).\n"
45" Pressing a hotkey more than once will sequence\n"
46" through all visible items which use that hotkey.\n"
47"\n"
48" You may also use the <PAGE UP> and <PAGE DOWN> keys to scroll\n"
49" unseen options into view.\n"
50"\n"
51"o To exit a menu use the just press <ESC> <F5> <F8> or <left-arrow>.\n"
52"\n"
53"o To get help with an item, press <F1>\n"
54" Shortcut: Press <h> or <?>.\n"
55"\n"
56"\n"
57"Radiolists (Choice lists)\n"
58"-----------\n"
59"o Use the cursor keys to select the option you wish to set and press\n"
60" <S> or the <SPACE BAR>.\n"
61"\n"
62" Shortcut: Press the first letter of the option you wish to set then\n"
63" press <S> or <SPACE BAR>.\n"
64"\n"
65"o To see available help for the item, press <F1>\n"
66" Shortcut: Press <H> or <?>.\n"
67"\n"
68"\n"
69"Data Entry\n"
70"-----------\n"
71"o Enter the requested information and press <ENTER>\n"
72" If you are entering hexadecimal values, it is not necessary to\n"
73" add the '0x' prefix to the entry.\n"
74"\n"
75"o For help, press <F1>.\n"
76"\n"
77"\n"
78"Text Box (Help Window)\n"
79"--------\n"
80"o Use the cursor keys to scroll up/down/left/right. The VI editor\n"
81" keys h,j,k,l function here as do <SPACE BAR> for those\n"
82" who are familiar with less and lynx.\n"
83"\n"
84"o Press <Enter>, <F1>, <F5>, <F7> or <Esc> to exit.\n"

87"Alternate Configuration Files\n"
88"-----------------------------\n"
89"nconfig supports the use of alternate configuration files for\n"
90"those who, for various reasons, find it necessary to switch\n"
91"between different kernel configurations.\n"
92"\n"
93"At the end of the main menu you will find two options. One is\n"
94"for saving the current configuration to a file of your choosing.\n"
95"The other option is for loading a previously saved alternate\n"
96"configuration.\n"
97"\n"
98"Even if you don't use alternate configuration files, but you\n"
99"find during a nconfig session that you have completely messed\n"
100"up your settings, you may use the \"Load Alternate...\" option to\n"
101"restore your previously saved settings from \".config\" without\n"
102"restarting nconfig.\n"
103"\n"
104"Other information\n"
105"-----------------\n"
106"If you use nconfig in an XTERM window make sure you have your\n"
107"$TERM variable set to point to a xterm definition which supports color.\n"
108"Otherwise, nconfig will look rather bad. nconfig will not\n"
109"display correctly in a RXVT window because rxvt displays only one\n"
110"intensity of color, bright.\n"
111"\n"
112"nconfig will display larger menus on screens or xterms which are\n"
113"set to display more than the standard 25 row by 80 column geometry.\n"
114"In order for this to work, the \"stty size\" command must be able to\n"
115"display the screen's current row and column geometry. I STRONGLY\n"
116"RECOMMEND that you make sure you do NOT have the shell variables\n"
117"LINES and COLUMNS exported into your environment. Some distributions\n"
118"export those variables via /etc/profile. Some ncurses programs can\n"
119"become confused when those variables (LINES & COLUMNS) don't reflect\n"
120"the true screen size.\n"
121"\n"
122"Optional personality available\n"
123"------------------------------\n"
124"If you prefer to have all of the kernel options listed in a single\n"
125"menu, rather than the default multimenu hierarchy, run the nconfig\n"
126"with NCONFIG_MODE environment variable set to single_menu. Example:\n"
127"\n"
128"make NCONFIG_MODE=single_menu nconfig\n"
129"\n"
130"<Enter> will then unroll the appropriate category, or enfold it if it\n"
131"is already unrolled.\n"
132"\n"
133"Note that this mode can eventually be a little more CPU expensive\n"
134"(especially with a larger number of unrolled categories) than the\n"
135"default mode.\n"
