为什么DMA模式打不开啊?我装完XP后打不开硬盘的DMA模式啊,CMOS中已将主从设备UDMA都设成了AUTO了,在XP系统中也已经将设备管理器中主从设备改为DMA(若可用)了,怎么办啊???速度好慢啊... |

解决办法：在控制面板、系统、硬件、设备管理、IDE ATA控制器、主要IDE通道、双击（或者按右键查看属性）、高级设置、你会看到你的硬盘是pio传输模式，而且不能改变为DMA模式。
确定退出。对“IDE主要通道”按右键卸载。重新启动。让XP自动安装硬盘驱动，你再看一下你的传输模式，感觉一下你机器速度是不是非常快了？：）
crt显示器和硬盘的传输模式没有关系 |

首先确定bios已经启用了udma5
数据线要80针的！
如果还不行，打开记事本，复制下面的注册表项,保存为.reg格式的文件，双击运行即可。
