For these 4 IDE option choose "Auto" to have the system BIOS auto
detect the IDE HDD operation mode for PIO access.
Note: Some IDE HDD can not operate at the responding HDD's mode.
When the user has selected "Auto" and the system BIOS has accepted the
HDD response mode the user may degrade the HDD's operation mode.
Ex: IF the HDD reported it can operate in mode 4 but it is not operating
properly the user will have to manually change the operation mode to mode
3.
Choosing Mode 1-4 will have the system ignore the HDD's reported
operation mode and use the mode selected instead.
Note: According to ATA specs. Mode 4 transfer rate is > Mode 3 > Mode 2
> Mode 1 > Mode 0. If the user's HDD can operate at Mode 3 the user can
also select a slower Mode (ie Mode 0-2) but not a faster Mode (ie Mode 4).
