Ø IDE Primary/Secondary 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

software both support Ultra DMA-33/66/100/133, select
Auto to enable UDMA mode by BIOS.

Automatic data transfer between system memory and IDE
device with minimum CPU intervention. This improves data
throughput and frees CPU to perform other tasks.

commands, or multiple sector read/write. If your IDE hard
drive supports block mode (most new drives do), select
