Chapter 4: BIOS
4-7
BIOS to use PIO mode 4. It has a data transfer rate of 16.6 MBs. This setting
generally works with all hard disk drives manufactured after 1999. For other disk
drives, such as IDE CD-ROM drives, check the specifi cations of the drive.
DMA Mode
Selects the DMA Mode. Options are SWDMA0, SWDMA1, SWDMA2,
MWDMA0. MDWDMA1, MWDMA2, UDMA0. UDMA1, UDMA2, UDMA3,
UDMA4 and UDMA5. (SWDMA=Single Word DMA, MWDMA=Multi Word DMA,
UDMA=UltraDMA.)
S.M.A.R.T.
Self-Monitoring Analysis and Reporting Technology (SMART) can help predict
impending drive failures. Select "Auto" to allow BIOS to auto detect hard disk
drive support. Select "Disabled" to prevent AMI BIOS from using the S.M.A.R.T.
Select "Enabled" to allow AMI BIOS to use the S.M.A.R.T. to support hard drive
disk. The options are Disabled, Enabled, and Auto.
32-Bit Data Transfer
Select "Enabled" to activate the function of 32-Bit data transfer. Select "Disabled"
to deactivate the function. The options are Enabled and Disabled.
Serial ATA0/1/2 Primary/Secondary Channel
Highlight one of the items above and press <Enter> to access the submenu for that
item. If a drive is present, information on that drive will be displayed here.
Type
Select the type of device connected to the system. The options are Not Installed,
Auto, CDROM and ARMD.
LBA/Large Mode
LBA (Logical Block Addressing) is a method of addressing data on a disk drive.
The options are Disabled and Auto.
Block (Multi-Sector Transfer)
Block mode boosts IDE drive performance by increasing the amount of data
transferred. Only 512 bytes of data can be transferred per interrupt if block mode
is not used. Block mode allows transfers of up to 64 KB per interrupt. Select
Disabled to allow the data to be transferred from and to the device one sector
at a time. Select Auto to allows the data transfer from and to the device occur
multiple sectors at a time if the device supports it.
