Internal Modem Installation with Windows 3.x

5.Find an empty ISA expansion slot that’s at least as long as the gold edge of your modem. (ISA slots are dark plastic grooves lined with metal.) Unscrew and remove the expansion slot cover. It is the long narrow piece of metal that keeps dust from entering through the opening perpendicular to the slot.

6.Holding the modem by each corner, align the gold edge with the empty expansion slot. Push down gently until the modem snaps into the slot. The diagram shows horizontally aligned expansion slots. Some computers have vertically aligned slots. The instructions apply to both styles.

You need to apply a little pressure to seat the modem properly. Sometimes a gentle back and forth motion helps fit the modem all the way into the slot. If you feel resistance, the modem may not be properly lined up with the slot. Do not force it into the slot. Remove the modem and try again.
