13.1. Intel 852GM GMCH RSVD Signals
Intel 852GM has a total of 32 RSVD and 12 NC signals that are Intel reserved in the pin-map. The
recommendation is to provide test points for all RSVD signals. All NC signals should be left as no
connects. The location of the Intel reserved signals in the GMCH pin-map is listed in Table 97.
