Hi everybody,
I have got a tablet with special frontkeys and I would like to install
and adapt android on it. This works fine with the project android-x86.org
On grub I would like to select the bootitems with the frontkeys.
The frontkeys can be read with the following code (this is working,
file named readFrontKey.c).
#include <unistd.h>
#include <stdio.h>
#include <stdlib.h>
#include <sys/io.h>
int main()
{
unsigned char bits8, bits9, bits0, bitsA, bitsB, bitsC, bitsD,
bitsE, bits;
if(ioperm(0x208, 8, 1) < 0) {
perror("0x208");
return 1;
}
bits = 32;
outb(bits, 0x20A);
outw(-16832, 0x20C);
bits9 = inb(0x209);
return bits9;
}
But when I add the following code to external/grub/stage2/stage2.c I get an
"undefined reference to `system' " error message:
The code I added to stage2.c (at roundabout line 391) is
bits9 = system("readFrontKey");
if (bits9 == 64)
entryno = 1;
if (bits9 == 32)
entryno = 2;
if (bits9 == 16)
entryno = 3;
goto boot_entry;
/* Check for a keypress, however if TIMEOUT has been expired
(GRUB_TIMEOUT == -1) relax in GETKEY even if no key has been
pressed.
stage2.c has stdlib.h included.
I added the program readfrontkey.c to Makefile.am and also adapted
Makefile.in
Any help woud be apreciated
