Description

Block mode boosts IDE drive performance by increasing the amount of data

transferred. Only 512 bytes of data can be transferred per interrupt if block mode

is not used. Block mode allows transfers of up to 64 KB per interrupt.

Select "Disabled" to allow the data to be transferred from and to the device one

sector at a time. Select "Auto" to allows the data transfer from and to the device

occur multiple sectors at a time if the device supports it. The options are Auto

and D

ISABLED

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.

Selects the DMA Mode. The only option is Auto

Self-Monitoring Analysis and Reporting Technology (SMART) can help predict

impending drive failures. Select "Auto" to allow BIOS to auto detect hard disk

drive support. Select "Disabled" to prevent AMI BIOS from using 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 D

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

to deactivate the function. The options are Enabled and D

This setting enables/disables device write protection and is effective only if the

device is accessed through BIOS. The default is Disabled.

This setting allows you to select the time out value for detecting ATA?ATAPI

devices. Press + or - on your keyboard to change this value. The default is 35.

This setting allows you to select the mechanism for detecting 80P in ATA(PI)

cable to either H
