Chapter 4: BIOS

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 specifi cations of the drive.

the S.M.A.R.T. Select "Enabled" to allow AMI BIOS to use the S.M.A.R.T.

to support hard drive disk. The options are Disabled, Enabled, and Auto.

32-Bit Data Transfer

Select "Enabled" to activate the function of 32-Bit data transfer. Select

"Disabled" to deactivate the function. The options are Enabled and Disabled.
