The four fields allow you to set a PIO (Programmed Input/Output) mode

IDE HDD Block Mode
This setting allows your hard disk controller to use the fast block mode to
transfer data to and from the hard disk drive. Block mode is also called

lecting enabled mode enables the IDE controller to use block mode; Dis-
abled mode allows the controller to use standard mode.
