1st) Where to save an array?
=============================
If I mimic the grub legacy map command I need to save an array with the
map definitions.
static unsigned short bios_drive_map[DRIVE_MAP_SIZE + 1];
So that each time I call something like:
map (hd0) (hd1)
it modifies this vector.
Any example on where should I define this vector so that I can use it
from each command ?
I ask the question again.
I've begun to implement commands/i386/pc/map.c (I suppose the map.c is
pc specific althought I am not sure).
The question is how do I get the bios number for a given hard disk?
Thank you. You know hd0 is usually 0x80, that's the number that I want.
Here is the source code written so far which I have not compiled.

static grub_err_t
grub_cmd_map (struct grub_arg_list *state __attribute__ ((unused)),
int argc, char **args)
{
grub_disk_t map_disk_1,map_disk_2;
if (argc != 2)
return grub_error (GRUB_ERR_BAD_ARGUMENT, "Two devices required");
map_disk_1 = grub_disk_open (args[0]);
if (! map_disk_1)
return grub_error (GRUB_ERR_UNKNOWN_DEVICE, "Unknown 1st disk");
map_disk_2 = grub_disk_open (args[1]);
if (! map_disk_2)
return grub_error (GRUB_ERR_UNKNOWN_DEVICE, "Unknown 2nd disk");
