IDE Master/Slave UDMA
Select the mode of operation for the IDE drive. Ultra DMA-
33/66/100/133 implementation is possible only if your IDE
hard drive supports it and the operating environment
includes a DMA driver. If your hard drive and your system
software both support Ultra DMA-33/66/100/133, select Auto
to enable UDMA mode by BIOS.
IDE HDD Block Mode
Block mode is also called block transfer, multiple commands,
or multiple sectors read/write. If your IDE hard drive
supports block mode (most new drives do), select
Enabled for automatic detection of the optimal number of
block read/writes per sector the drive can support.
