Ultra DMA/33 implementation is possible only if your IDE hard drive
supports it and the operating environment includes a DMA driver (Win-
dows 95 OSR2 or a third-party IDE bus master driver). If your hard drive
and your system software both support Ultra DMA/33 and Ultra DMA/66
and Ultra DMA/100, select Auto to enable BIOS support. The settings
are: Auto (Default), Disabled.
