**5597/5598      (Jedi)    Pentium PCI/ISA Chipset           <04/15/97
***Info:
Nowadays, several PC  form factors exist in the  PC board market, such
as  NLX, LPX,  ATX  and Baby-AT  form  factors. Due  to the  different
placements  of the  form factor,  PC chipsets  should be  prepared for
different board  layouts. As a  result, SiS chips based  on compatible
logic design provide two series of chipsets, SiS 5597 and SiS 5598, to
assist board designers for their board layouts.

SiS 5597’s pin assignment is based  on NLX, and LPX form factor, while
SiS 5598’s is defined on the basis of ATX and Baby-AT form factors. In
the next few chapters, you will read “SiS Chip” which indicates either
SiS 5597 or  5598 chipsets, decided by the  placements of form factors
on PC boards of customers.

The  SiS Chip  with built-in  VGA  controller is  a highly  integrated
single chip solution for Pentium PCI/ISA system. A portion of on-board
DRAM is  shared with the integrated  VGA controller. In  that way, the
system cost  is substantially  reduced and on-board  DRAM can  be used
flexibly.

The  SiS Chip  consists of  Host-to-PCI  bridge function,  PCI to  ISA
bridge  function,  PCI IDE  function,  Universal  Serial Bus  host/hub
function, Integrated RTC, Integrated Keyboard Controller and Graphics/
Video accelerate function.

SiS Chip  supports Enhanced  Power Management, including  legacy Power
Management  Unit  and   Advanced  Configuration  and  Power  Interface
(ACPI).  It also  supports ATA  Synchronous DMA  transfer  protocol to
improve  the IDE performance  and Common  Architecture for  moving ISA
function to PCI to improve system performance.
