Hi, Perhaps you can dump the biosdisk information as well #include <grub/machine/biosdisk.h> ... struct grub_biosdisk_data *data = (struct grub_biosdisk_data *) dev->disk->data then print its members (drive, cylinders, heads, sectors, flags). Also, please try copy the boot sector to a file and chainload it. -- Bean _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel
