This allows you to 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 or you can manually disable it.
Options: Auto, Disabled.

sector the drive can support.
