Word DMA mode 1. It has a data transfer rate of
4.2 MBs.
SWDMA2 Set this value to allow the BIOS to use Single
Word DMA mode 2. It has a data transfer rate of
8.3 MBs.
MWDMA0 Set this value to allow the BIOS to use Multi Word
DMA mode 0. It has a data transfer rate of 4.2
MBs.
MWDMA1 Set this value to allow the BIOS to use Multi Word
DMA mode 1. It has a data transfer rate of 13.3
MBs.
MWDMA2 Set this value to allow the BIOS to use Multi Word
DMA mode 2. It has a data transfer rate of 16.6
MBs.
UDMA0 Set this value to allow the BIOS to use Ultra DMA
mode 0. It has a data transfer rate of 16.6 MBs.
It has the same transfer rate as PIO mode 4 and

S.M.A.R.T. for Hard disk drives
Self-Monitoring Analysis and Reporting Technology
(SMART) feature can help predict impending drive
failures.
Option Description
Auto Set this value to allow the BIOS to automatically
detect hard disk drive support. Use this setting if
the IDE disk drive support cannot be determined.
This is the default setting.
Disabled Set this value to prevent the BIOS from using the
SMART feature.
Enabled Set this value to allow the BIOS to use the SMART
feature on support hard disk drives.
