Dear developers:
I'm trying to install a new bootloader on a computer. My angle was to write it to the zero address of the CMOS as follows, but the result is a SEGMENTATION FAULT. How do I write to the zero address using C?
-- CODE --
#include <stdio.h>
int main (int argc, char* argv[]) {
unsigned char* mem;
FILE* load;
mem = 0;
load = fopen("bootloader", "r");
while (!feof(load)) {
*mem = getc(load);
mem++;
}
fclose(load);
}
-- END OF CODE --
It should just do this, but it doesn't. What stands in my way? C is a low level programming language that's advertised as being suitable for system programming, which would include a bootloader. I did make sure to include the bootloader in the same directory as the executable.
Kind regards,
