First, sorry that I don't know how to type Chinese. But I fully know how to read.
Second, about the flashing process:
Open the cover of your machine.
Find out the label on your cd rom,record the maker and model number of it.
Go the google and type in "fireware+xxxx+yyyy", where xxxx is the maker and yyyy is the model number to find the latest firmware.
Download the firmware and follow their instruction to flash the firmware.
If you feel you are not familiar or no confidence with the process, find some friend to help you.
