Primary/Secondary Master/Slave UltraDMA
UDMA (Ultra DMA) is a DMA data transfer protocol that utilizes
ATA commands and the ATA bus to allow DMA commands to transfer data
at a maximum burst rate of 33MB/s. When you select Auto in the four IDE
UDMA fields (for each of up to four IDE devices that the internal PCI IDE
interface supports,) the system automatically determines the optimal data
transfer rate for each IDE device.
IDE Burst Mode
Selecting Enabled reduces latency between each drive read/write
cycle, but may cause instability in IDE subsystems that cannot support such
fast performance. If you are getting disk drive errors, try setting this value
to Disabled. This field does not appear when the Internal PCI/IDE field,
above is Disabled.
