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.
|
||
|
|
