The info and features section have  been solely sourced from the first
source.   The  second source  provides  far  more detail.   Additional
information in the configurations section  and below have been sourced
from the second.

"Although the 82497 Cache Controller  is part of the Pentium processor
(735\90, 815\100, 1000\120, 1110\133) CPU-Cache Chip Set and the 82496
Cache  Controller is part  of the  Pentium Processor  (510\60, 567\66)
Chip  Set, the  two parts  are functionally  identical except  for the
differences noted in this section." - p491

Aside  from some  minor  differences in  pin  configuration, the  main
difference is the direct support  for 3.3V processors. This chipset is
still a 5V part. The cache operates at bus speed, max 66MHz.


This  chip was  used on  the Pentium  90MHz CPU  complexes of  Intel's
Xpress  platform.   Specifically  the BXCPUPENT90  (Single  90MHz,  16
82492s). Also found on IBM 9595/Server 500 Pentium 90MHz complexes.

***Notes:...
***Info:
SiS5595  is a  highly integrated  system I/O  that constitutes  a high
performance, rich featured, yet glueless solution for both Pentium and
Pentium  II  systems.   

The SiS5595 PCI  system I/O integrates the PCI-to-ISA  bridge with the
DDMA and PC/PCI  DMA, Serial IRQ capability, the  ACPI/Legacy PMU, the
Data  Acquisition   Interface,  the  Universal   Serial  Bus  host/hub
interface,  and the  ISA bus  interface,  which contains  the ISA  bus
controller, the  DMA controllers,  the interrupt controllers,  and the
Timers.  It also integrates the Keyboard controller, and the Real Time
Clock (RTC).  The built-in USB controller, which is fully compliant to
OHCI (Open Host Controller  Interface), provides two USB ports capable
of running full/low speed  USB devices. The Data Acquisition Interface
offers  the  ability of  monitoring  and  reporting the  environmental
condition  of the  PC.  It  could monitor  5  positive analog  voltage
inputs, 2  Fan speed inputs,  and one external temperature  inputs. It
also integrates the automatic power control logic to control the power
ON/OFF for ATX power supply.  In addition, SiS5595 also integrates the
thermal  detection and frequency  ratio control  logic for  Pentium II
CPU.
