Ultra DMA Mode 5 capable and status bad 翻译意思是 高速存畜模式 5 有能力的和状态坏 应该是说硬盘或内存问题，如果你能开机的话那说明你的硬盘还是好的可能有部分区损坏用软件修下 要是再不行内存拆了过半小时再装上去

这个提示是硬盘线的问题，你换个硬盘线试下。那么，你检查下硬盘的数据线接口有没有问题，可能的话，换个电源测试下。
I am having issues with applying a BitLocker encryption to my device. When i checked the System information i found the reason is Un-allowed DMA capable bus/device(s) detected. How can i solve it? I saw a walkaround with registry but is there another solution?
DMA-capable devices require more registers than were used in the previous examples.The following fields are used in the device register structure to support DMA-capable device with no scatter-gather support:uint32_t dma_addr; /* starting address for DMA */ uint32_t dma_size; /* amount of...
