**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.

**SL82C460   'Haydn II' 80486 chipset   [no datasheet]         c:Jun91
***Notes:
from:
http://www.cbronline.com/news/symphony_introduces_the_haydn_family

"Santa Clara, California-based  Symphony Laboratories Inc has unvieled
a family  of highly integrated core  logic chip sets for  all forms of
AT-alike personal  computers: the Haydn family  comprises the SL82C460
set for  80486 systems and the  SL82C360 set for  80386 machines; each
set includes two devices, a system controller and a bus controller and
an optional cache controller chip  can be added if cache capability is
required;  the   parts  are  in  volume  production   and  a  complete
motherboard can be created with as few as eight active components plus
memory; all operate at 50MHz and  beyond and the sets are supported by
all  major BIOS  vendors; the  sets cost  from $50  to $100  apiece in
quantities of 100-up."
