Do I need to wait for status of or something here?
Something is not switching the registers and with outer lba it fills the
non-hob registers with zeros and this is not cool!
OUT_BYTE(hobfile->sector_count, IDE_NSECTOR_REG);
OUT_BYTE(hobfile->sector_number, IDE_SECTOR_REG);
OUT_BYTE(hobfile->low_cylinder, IDE_LCYL_REG);
OUT_BYTE(hobfile->high_cylinder, IDE_HCYL_REG);
OUT_BYTE(hobfile->device_head, IDE_SELECT_REG);
ide_set_handler (drive, handler, WAIT_CMD, NULL);
OUT_BYTE(taskfile->command, IDE_COMMAND_REG);
Either the method is wrong or the order of operations is wrong,
regardless. I am looking for a clue.
