Type [Auto] Allows you to select the type of device installed. [Not Installed] [Auto] [CDROM] [ARMD] Select this option if no device is installed. Allows automatic selection of the appropriate device type. Select this option if you are specifically configuring a CD-ROM drive. Select [ARMD] (ATAPI Removable Media Device) if your device is either a ZIP, LS-120, or MO drive. This item appears in SATA 5/SATA 6 only. LBA/Large Mode [Auto] [Auto] Select [Auto] to enable the LBA mode (Logical Block Addressing mode) if the device supports this mode, and if the device was not previously formatted with LBA mode disabled. [Disabled] Disables this function. 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. 3-12 Chapter 3: BIOS setup Chapter 3 E5888_M4A88TD-V EVO-USB3_Content12 12 5/26/10 3:45:33 PM
