IDE Secondary Master PIO
Auto/Mode0/Mode1-4
IDE Secondary Slave PIO
Auto/Mode0/Mode1-4
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 selected mode 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 (i.e. Mode 0-2) but not a faster
Mode (ie Mode 4).
