Linux檢視硬體資訊

1. 最簡單的的顯示全部dmi資訊：

<b> # dmidecode</b>

這樣将輸出所有的dmi資訊，你可能會被一大堆的資訊吓壞，通常可以使用下面的方法。

2.更精簡的資訊顯示：

<b># dmidecode -q</b>

-q(--quite) 隻顯示必要的資訊，這個很管用哦。

3.顯示指定類型的資訊：

通常我隻想檢視某類型，比如CPU，記憶體或者磁盤的資訊而不是全部的。這可以使用-t(--type TYPE)來指定資訊類型：

<b># dmidecode -t bios</b>

# dmidecode -t bios, processor (這種方式好像不可以用，必須用下面的數字的方式)

<b># dmidecode -t 0,4</b>  (顯示bios和processor)

伺服器到底能擴充到多大的記憶體？

[root@TJSJHL218-154 setup]# dmidecode -t 16

# dmidecode 2.9

SMBIOS 2.5 present.
