1. 最简单的的显示全部dmi信息：
# dmidecode
这样将输出所有的dmi信息，你可能会被一大堆的信息吓坏，通常可以使用下面的方法。
2.更精简的信息显示：
# dmidecode -q
-q(--quite) 只显示必要的信息，这个很管用哦。
3.显示指定类型的信息：
通常我只想查看某类型，比如CPU，内存或者磁盘的信息而不是全部的。这可以使用-t(--type TYPE)来指定信息类型：
# dmidecode -t bios
# dmidecode -t bios, processor (这种方式好像不可以用，必须用下面的数字的方式)
# dmidecode -t 0,4 (显示bios和processor)
服务器到底能扩展到多大的内存？
