BIOS Setup IDE setting details Type [Auto] Select Auto to automatically detect an IDE type drive. This option only works with standard built-in IDE drives. If automatic detection is successful, the correct values will be filled in for the remaining fields on this sub-menu. The configuration options are: [Not Installed] [Auto] [CDROM] [ARMD] LBA/Large Type [Auto] When Logical Block Addressing is enabled, 28-bit addressing of the hard drive is used without regard for cylinders, heads, or sectors. Note that Logical Block Access may decrease the access speed of the hard disk. However, LBA Mode is necessary for drives with greater than 504MB in storage capacity. The configuration options are: [Disabled] [Auto] Block [Auto] Auto automatically sets the number of sectors per block to the highest number supported by the drive. Disabled - The data transfer from and to the device occurs one sector at a time. Auto - The data transfer from and to the device occurs multiple sectors at a time if the device supports it. The configuration options are: [Disabled] [Auto] PIO Mode [Auto] When enabled, this option speeds up communication between the system and the IDE controller by using enhanced I/O transfer modes (PIO Modes). Different speeds are supported by different generations of IDE devices. The configuration options are: [Auto] [0] [1] [2] [3] [4] DMA Mode [Auto] When enabled, this option speeds up communication between the system and the IDE controller by using DMA capability (for improved transfer speeds and data integrity) . Different speeds are supported by different generations of IDE devices. SW = Single Word, MW = Multiple Word, U = Ultra Mode 0 = 16.7MB/s Mode 1 = 25.0MB/s Mode 2 = 33.3MB/s (ATA/33) Mode 3 = 44.4MB/s Mode 4 = 66.7MB/s (ATA/66) Mode 5 = 100MB/s (ATA/100) The configuration options are: [Auto] [SWDMA0...2] [MWDMA0...2] [UDMA0...4] SMART Monitoring [Auto] Self-Monitoring Analysis and Reporting Technology (S.M.A.R.T.) is an interface between a computer's BIOS and hard disk. It is a feature of the Enhanced Integrated Drive Electronics (EIDE) technology that controls access to the hard drive. If S.M.A.R.T is enabled, the BIOS can receive analytical information from the hard drive and determine whether to send the user a warning message about possible future failure of the hard drive. Ideally, this should allow you to take proactive actions to prevent impending disk crashes. The configuration options are: [Auto] [Disabled] [Enabled] 32Bit Data Transfer [Enabled] Enables or disables 32-bit data transfers for supported devices. The configuration options are: [Disabled] [Enabled] 105
