32Bit data Transfer 应该是打开还是关闭啊??




俺对网上学习的解释:

大概的意思是对64位系统来说最好关闭.

不确认啊..........


大师们讨论一下32Bit data Transfer 应该是打开还是关闭啊??

divice:not detected。。。。。你硬盘都没装上去就可以研究哪个性能好？这跟躺在床上脑补火锅微辣和中辣哪个好吃有啥区别？

个人认为装上硬盘和系统，找个硬盘跑分软件enable跑一次、disable跑一次，比较一下分数不就知道了吗？

这什么古董机啊，竟然还有PIO选项
这个32位数据传输，跟32位64位系统不是一个概念啊，开启会比较好

你多看下搜索内容啊........
你应该是根据自己的理解分析的..........
应该还是俺说的........

This BIOS feature allows you to command the IDE controller to combine two 16-bit hard disk reads into a single 32-bit data transfer to the processor. This greatly improves the performance of the IDE controller as well as the PCI bus.
Therefore, it is highly advisable to enable 32-bit Transfer Mode. If you disable it, data transfers from the IDE controller to the processor will only occur in 16-bits chunks.

Details
This BIOS feature is similar to the 32-bit Disk Access BIOS feature. The name 32-bit Transfer Mode is actually a misnomer because it doesn’t really allow 32-bit transfers on the IDE bus.
The IDE interface is always 16-bits in width even when the IDE controller is on the 32-bit PCI bus. What this feature actually does is command the IDE controller to combine two 16-bit reads from the hard disk into a single 32-bit double word transfer to the processor. This allows the PCI bus to be more efficiently used as the number of transactions required for a particular amount of data is effectively halved!

这个和32位64位系统无关。强烈建议开启，否则DOS状态读写盘速度会减慢，Windows开机速度也会有影响（加载保护模式磁盘驱动前，系统文件加载速度会变慢）
