DMA Mode
This setting allows you to adjust the DMA mode options. The Optimal and Fail-Safe
default setting is
Auto
.
Option Description
Auto
Set this value to allow the BIOS to auto detect the DMA mode. Use this value if the IDE disk
drive support cannot be determined. This is the default setting.
SWDMA0
Set this value to allow the BIOS to use Single Word DMA mode 0. It has a data transfer rate of
2.1 MBs.
SWDMA1
Set this value to allow the BIOS to use Single Word DMA mode 1. It has a data transfer rate of
4.2 MBs.
SWDMA2
Set this value to allow the BIOS to use Single Word DMA mode 2. It has a data transfer rate of
8.3 MBs.
MWDMA0
Set this value to allow the BIOS to use Multi Word DMA mode 0. It has a data transfer rate of
4.2 MBs.
MWDMA1
Set this value to allow the BIOS to use Multi Word DMA mode 1. It has a data transfer rate of
13.3 MBs.
MWDMA2
Set this value to allow the BIOS to use Multi Word DMA mode 2. It has a data transfer rate of
16.6 MBs.
UDMA0
Set this value to allow the BIOS to use Ultra DMA mode 0. It has a data transfer rate of 16.6
MBs. It has the same transfer rate as PIO mode 4 and Multi Word DMA mode 2.
UDMA1
Set this value to allow the BIOS to use Ultra DMA mode 1. It has a data transfer rate of 25 MBs.
UDMA2
Set this value to allow the BIOS to use Ultra DMA mode 2. It has a data transfer rate of 33.3
MBs.
UDMA3
Set this value to allow the BIOS to use Ultra DMA mode 3. It has a data transfer rate of 44.4
MBs. To use this mode, it is required that an 80-conductor ATA cable is used.
UDMA4
Set this value to allow the BIOS to use Ultra DMA mode 4. It has a data transfer rate of 66.6
MBs. To use this mode, it is required that an 80-conductor ATA cable is used.
UDMA5
Set this value to allow the BIOS to use Ultra DMA mode 5. It has a data transfer rate of 99.9
MBs. To use this mode, it is required that an 80-conductor ATA cable is used.
UDMA6
Set this value to allow the BIOS to use Ultra DMA mode 6. It has a data transfer rate of 133.2
MBs. To use this mode, it is required that an 80-conductor ATA cable is used.
S.M.A.R.T. for Hard Disk Drives
Self-Monitoring Analysis and Reporting Technology (SMART) feature can help predict
impending drive failures. The Optimal and Fail-Safe default setting is
Auto
.
Option Description
Auto
Set this value to allow the BIOS to auto detect hard disk drive support. Use this setting if the
IDE disk drive support cannot be determined. This is the default setting.
Disabled
Set this value to prevent the BIOS from using the SMART feature.
Enabled
Set this value to allow the BIOS to use the SMART feature on support hard disk drives.
