BIOS Setup Utility

∗If [Auto] is selected, the BIOS will auto detect the number of sectors per block for transfer from the hard disk drive to the memory. The data transfer to and from the device will occur multiple sectors at a time.

♦PIO Mode – [Auto], [0], [1], [2], [3], or [4]

This field sets the IDE PIO (Programmable I/O) mode and programs the timing cycles between the IDE drive and the programmable IDE controller. As the PIO mode increases, the cycle time decreases.

∗If [Auto] is selected, the BIOS auto detects the PIO mode.

∗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], [UDMA2], [UDMA3], [UDMA4], [UDMA5], or [UDMA6]

This field allows you to select DMA modes and adjust the respective transfer rate. The list of available DMA modes are dependent on the IDE device and its supported modes, including the transfer speed and cable type (40-pin or 80-pin).

∗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 Double Word DMA mode 0, with a data transfer rate of 4.2 MBs.

∗If [MWDMA1] is selected, the BIOS uses Double Word DMA mode 1, with a data transfer rate of 13.3 MBs.

∗If [MWDMA2] is selected, the BIOS uses Double 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

16.6MBs.

∗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

33.3MBs.

NOTE

If you select UDMA3, UDMA4, UDMA5, or UDMA6, an 80-conductor

 

ATA cable is required.

∗If [UDMA3] is selected, the BIOS uses Ultra DMA mode 3, with a data transfer rate of

44.4MBs. To use this mode, an 80-conductor ATA cable is required.

∗If [UDMA4] is selected, the BIOS uses Ultra DMA mode 4, with a data transfer rate of

66.6MBs. To use this mode, an 80-conductor ATA cable is required.
