oh no, i was wrong, forget me
Thanks for the information, i try to fix it.
Another funny thing:
in ./grub-core/kern/emu/hostdisk.c:
disk->total_sectors = grub_util_get_fd_size (fd, map[drive].device, &disk->log_sector_size); disk->total_sectors >>= disk->log_sector_size;
second line is overwrite the value of previous life :-)

want to print out something in ./grub-core/kern/disk_common.c, so i do
"grub_util_info("peter\n");" and add "include <grub/util/misc.h>" on the top
of the file, but i get this error:
In file included from lib/../kern/disk_common.c:1:0,
from lib/disk.c:31:
../include/grub/util/misc.h:22:20: fatal error: stdlib.h: No such file or
directory
disk_common is unrelated to your problem. You need to look at host device probing code under grub-core/osdep, code that maps host device to grub device is historically located in various getroot.c files.
May I know the correct way to print out something please?
#ifdef GRUB_UTIL grub_util_info (...); #endif thanks

No, it is not the same message. Now it correctly detects disk2, but it
lacks MAC OS X specific code for BIOS device guessing.
grub-install expects device.map in /boot/grub; so put it there (i.e. on
filesystem on /dev/disk2s1).
Someone more familiar with OS X need to contribute device detection code
for it.
