Remove ancient documentation of IBM RapidAccess keyboard hack
Keyboard setup belongs in drivers, not in a document no one sees because we don't even install it. Signed-off-by: Alan Coopersmith <alan.coopersmith@oracle.com> Reviewed-by: Julien Cristau <jcristau@debian.org> Reviewed-by: Alex Deucher <alexdeucher@gmail.com>

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.
|
|
||||||
