This is a demonstration of how INT 13, ah=42 fails after a while. | |
Run 'bash debug.sh`, then hit `c` a couple of times, you should | |
see that INT 13 returns with CF set, which means it had an error. | |
Why is it happening? The code is pretty simple, all it does is reading | |
a sector from the disk, and copying it to some place in the memory. |
