Fast Programmed I/O Modes

Option name:

Fast Programmed I/O Modes

Possible values of an option:

[Auto], [0], [1], [2], [3], [4]
Or
[Auto], [Mode 0], [Mode 1], [Mode 2], [Mode 3], [Mode 4]

The option description:

The given option allows to specify a data interchange mode (PIO Mode — Programmed Input/Output Mode) with the drive connected to the given channel of the standard IDE/SATA-controler of a chipset of the motherboard. As a rule, it is possible to use a mode of automatic determination of the maximum possibilities of the connected drive ([Auto]). In case of problems with the given specific disk it is possible to use sequentially slower, but also more reliable, in respect of compatibility with the old equipment, modes (maximum — [4] or [Mode 4], minimum — [0] or [Mode 0]).

For help we result the maximum speed of a data interchange with the drive of interface IDE or SATA for each of modes:

PIO Mode 0 3.3 Mb/sek
PIO Mode 1 5.2 Mb/sek
PIO Mode 2 8.3 Mb/sek
PIO Mode 3 11.1 Mb/sek
PIO Mode 4 16.6 Mb/sek

All modern hard disks, and also optical disk drives and to it similar devices work in mode PIO Mode 4.

Other options identical to destination:

IDE Channel0 Master PIO

IDE Channel0 Slave PIO

IDE Channel1 Master PIO

IDE Channel1 Slave PIO

IDE Primary Master PIO

IDE Primary Slave PIO

IDE Secondary Master PIO

IDE Secondary Slave PIO

PIO Mode
