After you defeat the boss and get his key for the console you'll get the next puzzle to solve. There are 4 panels with chinese symbols on them, you have to get them in a certain order to unlock the case to get the computer disk. Look on the ledge you used to get into the room with the boss their are 4 chinese symbols above in what appear to be neon signs. Each lights up in a different order, left to right. Memorize that and use those four signals left to right on the console and you'll get the disc.
