PIO Mode
PIO (Programmable I/O) mode programs timing cycles between the IDE drive
and the programmable IDE controller. As the PIO mode increases, the cycle time
decreases. The options are Auto, 0, 1, 2, 3, and 4. Select Auto to allow BIOS to
auto detect the PIO mode.
Use this value if the IDE disk drive support cannot be determined.
• Select 0 to allow BIOS to use PIO mode 0, which has a data transfer rate of
3.3 MBs.
• Select 1 to allow BIOS to use PIO mode 1, which has a data transfer rate of
5.2 MBs.
• Select 2 to allow BIOS to use PIO mode 2, which has a data transfer rate of
8.3 MBs.
• Select 3 to allow BIOS to use PIO mode 3, which has a data transfer rate of
11.1 MBs.
• Select 4 to allow BIOS to use PIO mode 4, which has a data transfer rate of
16.6 MBs.
This setting generally works with all hard disk drives manufactured after 1999.
For other disk drives, such as IDE CD-ROM drives, check the specifications of
the drive.
