Device 0 Register Bit Differences
The registers described in this section are in both the 82845G and 82845GL/82845GV. However,
some of the register bits have different functions/operations between the components. Only the bits
that are different are shown in this section. Thus, the bit descriptions shown in this section only
apply to the 82845GL or 82845GV. The remaining register bits are the same for all three
components and are described in

Integrated Graphics Disable (IGDIS). The GMCH’s Device 1 is disabled such that all
configuration cycles to Device 1 flow through to the hub interface. Also, the Next_Pointer field in
the CAPREG register (Device 0, Offset E4h) is RO at 00h. This enables internal graphics
capability.
0 = Enable. Internal Graphics is enabled (default)
