Type [Auto] Allows you to select the type of SATA drive installed. [Not Installed] [Auto] [CDROM] [ARMD] Select this option if no SATA drive is installed. Allows automatic selection of the appropriate SATA device type. Select this option if you are specifically configuring a CD-ROM drive. Select [ARMD] (ATAPI Removable Media Device) if your device is a ZIP, LS-120, or MO drive. LBA/Large Mode [Auto] Enables or disables the LBA (Logical Block Addressing) mode. [Auto] [Disabled] 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. Disables this function. Block (Multi-Sector Transfer) M [Auto] Enables or disables data multi-sector transfers. [Auto] [Disabled] When set to [Auto], the data transfer from and to the device occurs in multiple sectors at a time if the device supports the multi-sector transfer feature. 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] Set 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 very little 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 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 IDE 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. Chapter 3 3-10 Chapter 3: BIOS setup
