SInce my mainboard was dead, I replaced a new mainboard: http://www.pcchips.com.tw/M758LT+.html.
I checked with the hardware compatibility list of redhat.com. There is no pcchips.com.tw manufacturer.
Unluckily, there is no email contact nor technical support from PCChips.
The linux can be booted up and I can login. However, I cannot use the mouse and connect to the internet.
How can I fix these problems?
Thanks in advance.
