Block (Multi-Sector Transfer) M [Auto] [Auto] When set to [Auto], the data transfer from and to the device occurs in multiple sectors at a time if the device supports multi-sector transfer feature. [Disabled] When set to [Disabled], the data transfer from and to the device occurs one sector at a time. PIO Mode [Auto] [Auto] Allows automatic selection of the PIO (Programmed input/output) modes, which correspond to different data transfer rates. [0] [1] [2] [3] [4] Sets the PIO mode to Mode 0, 1, 2, 3, or 4. DMA Mode [Auto] DMA (Direct Memory Access) allows your computer to transfer data to and from the hardware devices installed with much less CPU overhead. The DMA mode consists of SDMA (single-word DMA), MDMA (multi-word DMA), and UDMA (Ultra DMA). Setting to [Auto] allows automatic selection of the DMA mode. SMART Monitoring [Auto] [Auto] Allows automatic selection of the S.M.A.R.T (Smart Monitoring, Analysis, and Reporting Technology). [Enabled] Enables the S.M.A.R.T feature. [Disabled] Disables the S.M.A.R.T feature. 32Bit Data Transfer [Enabled] [Enabled] Sets the controller to combine two 16-bit reads from the hard disk into a single 32-bit double word transfer to the processor. This makes more efficient use of the PCI bus as fewer transactions are needed for the transfer of a particular amount of data. [Disabled] Disables this function. 2.4.2 Storage Configuration The Storage Configuration menu allows you to configure your storage devices. Select an item then press to display the submenu. OnChip SATA Channel [Enabled] [Enabled] Enables the onboard channel SATA port. [Disabled] Disables the onboard channel SATA port. The following two items appear only when you set the OnChip SATA Channel item to [Enabled]. Chapter 2: BIOS setup 2-9
