Chapter 7: BIOS
7-1
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.
