DMA Mode
This setting allows you to adjust the DMA mode options. The Optimal and Fail-Safe default setting is Auto .
Auto Allows 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 Allows the BIOS to use Single Word DMA mode 0. It has a data transfer rate of 2.1 MBs.
SWDMA1 Allows the BIOS to use Single Word DMA mode 1. It has a data transfer rate of 4.2 MBs.
SWDMA2 Allows the BIOS to use Single Word DMA mode 2. It has a data transfer rate of 8.3 MBs.
MWDMA0 Allows the BIOS to use Multi Word DMA mode 0. It has a data transfer rate of 4.2 MBs.
MWDMA1 Allows the BIOS to use Multi Word DMA mode 1. It has a data transfer rate of 13.3 MBs.
MWDMA2 Allows the BIOS to use Multi Word DMA mode 2. It has a data transfer rate of 16.6 MBs.
UDMA0 Allows 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 Allows the BIOS to use Ultra DMA mode 1. It has a data transfer rate of 25 MBs.
UDMA2 Allows the BIOS to use Ultra DMA mode 2. It has a data transfer rate of 33.3 MBs.
UDMA3 Allows 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 Allows 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 Allows 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.
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 .
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.
32Bit Data Transfer
This option sets the 32-bit data transfer option. The Optimal and Fail-Safe default setting is Enabled .
Disabled Set this value to prevent the BIOS from using 32-bit data transfers.
Enabled Set this value to allow the BIOS to use 32-bit data transfers on support hard disk drives. This is the
default setting.
