Hello All,
I have a little problem, when I try to get my drive on boot (16bit) I
am getting the wrong address:
This code:
struct xendrive_s * xendrive =
GLOBALFLAT2GLOBAL(container_of(GET_GLOBAL(op->drive_g), struct
xendrive_s, drive));
dprintf(1,"Xendrive at:%p\n",xendrive);
Returns this:
Xendrive at:0xfff10000
But it should be this instead:
dprintf(1,"TEST drive 0 %p \n",i,GET_GLOBAL(xendrives[0]));
returns this:
TEST drive 0 0x000fd620
This last address is the address returned when done this:
struct xendrive_s *xd = malloc_fseg(sizeof(struct xendrive_s*));
SET_FLATPTR(xendrives[count_drives],xd);
The xd pointer is later used for:
boot_add_hd(&xd->drive,desc,drives);
Any tip to solve this will be greatly appreciated.
Thanks you all,
Daniel
