∗ If [0] is selected, the BIOS uses PIO mode 0, with a data transfer rate of 3.3 MBs.
∗ If [1] is selected, the BIOS uses PIO mode 1, with a data transfer rate of 5.2 MBs.
∗ If [2] is selected, the BIOS uses PIO mode 2, with a data transfer rate of 8.3 MBs.
∗ If [3] is selected, the BIOS uses PIO mode 3, with a data transfer rate of 11.1 MBs.
∗ If [4] is selected, the BIOS uses PIO mode 4, with a data transfer rate of 16.6 MBs.
• DMA Mode – [Auto], [SWDMA0], [SWDMA01], [SWDMA2], [MWDMA0],
[MWDMA1], [MWDMA2], [UDMA0], [UDMA1], or [UDMA2]
This field allows you to select DMA modes and adjust the respective transfer rate. The
list of DMA modes are dependent on the device's DMA characteristics.
SWDMAn = Single Word DMA mode n
MWDMAn = Muliti Word DMA mode n
UDMAn = Ultra DMA mode n
∗ If [Auto] is selected, the BIOS auto detects the DMA Mode. Use this value if the IDE
disk drive support cannot be determined.
∗ If [SWDMA0] is selected, the BIOS uses Single Word DMA mode 0, with a data
transfer rate of 2.1 MBs.
∗ If [SWDMA1] is selected, the BIOS uses Single Word DMA mode 1, with a data
transfer rate of 4.2 MBs.
∗ If [SWDMA2] is selected, the BIOS uses Single Word DMA mode 2, with a data transfer
rate of 8.3 MBs.
∗ If [MWDMA0] is selected, the BIOS uses Muliti Word DMA mode 0, with a data
transfer rate of 4.2 MBs.
∗ If [MWDMA1] is selected, the BIOS uses Muliti Word DMA mode 1, with a data
transfer rate of 13.3 MBs.
∗ If [MWDMA2] is selected, the BIOS uses Muliti Word DMA mode 2, with a data
transfer rate of 16.6 MBs.
∗ If [UDMA0] is selected, the BIOS uses Ultra DMA mode 0, with a data transfer rate of
16.6 MBs.
∗ If [UDMA1] is selected, the BIOS uses Ultra DMA mode 1, with a data transfer rate of
25 MBs.
∗ If [UDMA2] is selected, the BIOS uses Ultra DMA mode 2, with a data transfer rate of
33.3 MBs.
• S.M.A.R.T. – [Auto], [Disabled], or [Enabled]
The Self-Monitoring Analysis and Reporting Technology (SMART) feature can help
predict impending hard disk drive failures.
∗ If [Auto] is selected, the BIOS auto detects hard disk drive support. Use this setting if the
IDE disk drive support cannot be determined.
∗ If [Disabled] is selected, the BIOS is prevented from using SMART feature.
∗ If [Enabled] is selected, the BIOS uses the SMART feature on the hard disk, drives.
• 32Bit Data Transfer – [Disabled] or [Enabled]
This field sets the 32-bit data transfer rate.
If [Enabled] is selected, the BIOS uses 32-bit data transfers on the supported hard disk drive.
