[知識文] Through network to install OS Techology

You have a server and let other clients connect it to install OS.
if you put windows OS image in this server, it called WDS.
if you put linux OS image in this server, it called PXE.

方法很類似，同樣是透過網路安裝OS，名稱不太一樣。

[知識文] DeLL PowerEdge M820 install Red Hat 6.4

When install RHEL follow the default installation steps. And enter the software installation screen to click "custom now" to choose softwares to install. Don't check the optain "tboot"(it in base category). Otherwise it will be non-boot!! "tboot" is a method to verify for cisco(citrix) XenServer....I guess.

在Dell的PowerEdge 伺服器上裝RedHat的企業版--RHEL時，要注意安裝過程中，選擇Software，有一個項目是Base，選擇右下角的Option ，把tboot-xxxx(版本)取消掉，不然安裝結束後可能不能開機。

可是我只知道RHEL6.4和6.5裡有這東西，其他版本不確定。
