解决方法

拉到最下面有这么一段话:

Well, solved. Not sure exactly how I did it but have found the right combination in the end. Anyway, if someone else gets the same problem and wants to use that single PS/2 port on Gaming 7 motherboard in Win 7, you have to set it like this in BIOS:
1. Fast boot: ENABLED > also under Fast Boot set USB to ALL (not partial, to all) and PS/2 to ENABLED
2. XHCI - ENABLED
3. Legacy USB - DISABLED

大概的意思是,把PS2接口启用,同时把传统USB的功能禁用。

设置之后保存重启,PS2接口的键盘(鼠标)就能用了。但是有个问题,如果你要用USB2接口的U盘安装系统的话,这个时候是识别不了的。所以还是建议使用USB键盘为佳。
