Step 5 Orient and insert the new ROM in its socket, being careful to not bend or crush any of the bottom pins.
(See Figure 24.) Straighten any bent pins with a needlenose pliers. Align the notch in the new ROM
with the notch in the ROM socket, ignoring the orientation of the label.
Figure 24 Installing the ROM in the Mainboard
Caution The notch on the ROM must match the notch on the mainboard socket. Installing the ROM backward
damages the ROM, the router, or both.
