双敏k8t890n主板不支持SATA2直接

My computer was bought in June 2005, using the UNIKA K8T890N motherboard.I recently bought a WD 640GB SATA2 hard disk, and when the system was installed, I found that the hard disk could not be found.Look at the instructions and find that the motherboard supports only the SATA hard disk and does not support the SATA2 hard disk.Is there any solution to the transfer line to solve this problem

你的主板是通过k8t890 + VT8237R芯片组，因为VT8237R芯片不支持硬盘传输速率自动调整，所以直接连接SATA2硬盘主板肯定是无法识别的。我需要提醒你，尽管你的主板并不直接支持SATA2硬盘，硬盘调整SATA工作模式可以解决的问题，但经过调整后，硬盘的性能会下降。具体的调整方法是用跳线帽连接在硬盘电源接口左边5和6脚。
