82810E (GMCH)
• Graphics Controller Graphics Memory Range. The GMCH’s graphics controller device uses a
logical memory concept to access graphics memory. The logical graphics memory size is
programmable as either 32 MB or 64 MB and is allocated by BIOS during Plug and Play. This
address range is programmed in the GMADR Register (Device 1) and the MISCC Register
(Device 0). The graphics controller engines can access this address space of which the lower 32 MB
or all 64 MB correspond to graphics memory accessable by the processor.
