Using common defaults will reduce errors and maintenance. Only the very small or inexistent custom section need periodic maintenance when the structure of the component changes. Do not edit defaults.

The IBM Rapid Access keyboard have some extra buttons on it to launch programs, control a cd-player and so on. These buttons is not functional when the computer is turned on but have to be activated by sending the codes 0xea 0x71 to it. I've written the following hack to send codes to the keyboard: -------------------------------------------------------------- /* gcc -O2 -s -Wall -osend_to_keyboard send_to_keyboard.c */ #include <stdlib.h> #include <unistd.h> #include <sys/io.h> int main( int argc, char *argv[] ) { int i; ioperm( 0x60, 3, 1 ); for( i = 1; i < argc; i++ ) { int x = strtol( argv[i], 0, 16 ); usleep( 300 ); outb( x, 0x60 ); } return 0; } -------------------------------------------------------------- As root you can then call this program (in your boot scripts) as "send_to_keyboard ea 71" to turn on the extra buttons. It's not a good idea to run several instances of this program at the same time. It is a hack but it works. If you try to send other codes to the keyboard it probably will lock up.
