**5596/5513      (Genesis) Pentium PCI Chipset               <03/26/96
***Info:
The SiS5596/5513  with built-in VGA controller is  a two-chip solution
for Pentium PCI/ISA system. A portion  of on board DRAM is shared with
the  built-in  VGA  controller.  In  that  way,  the  system  cost  is
substantially reduced.

The SiS5596/5513 two chips  solution for shared memory architecture is
achieved by  allowing both  GUI / VGA,  and System DRAM  controller to
control system memory. For  the shared memory application, the chipset
always acts  as the  arbiter of memory  bus masters. Whenever  the GUI
wants to  access the memory bus,  it requests the memory  bus from the
chipset first.  The chipset grants the  memory bus to the GUI, only if
the memory bus is not needed by the chipset. The chipset also supports
the two priority  scheme. Other important key features  such as direct
access frame buffer and memory access latency are also supported.
