**82C556M/7M/8E Viper-N+ Viper Notebook Chipset c:96
***Notes:...
***Info:
The OPTi Viper-N+ chipset is the leading solution for PCI-based mobile
applications. Viper-N+ features leading edge power management
capability and flexibility for Intel Pentium 75/90/100/120 and Cyrix
6x86 processor based notebooks. The chipset incorporates desktop-like
performance features such as L1 and L2 cache support, a full 64-bit
DRAM controller and an integrated PCI controller, in a highly
integrated three chip set.
In terms of advanced power management, no chipset offers a more
effective, comprehensive or flexible feature set, allowing for maximum
performance with minimum power consumption for extended battery
life. In fact, for typical applications, Viper-N+'s power management
unit reduces power consumption by as much as 80%.
Viper-N+ offers the highest level of system integration, enabling the
lowest system cost and real estate requirement for Pentium-PCI
notebooks. A system without TTL is achievable with synchronous cache.
And, PCI offers easy upgradability to emerging standard interfaces,
such as PCMCIA/CardBus and PCI docking stations. Viper-N+ also
features an integrated local bus IDE controller to avoid ISA data bus
bottlenecks.
OPTi coupled its expertise in mobile technology and PCI-based design
to create its second generation 64-bit CPU mobile chipset. The result
is Viper-N+, enabling the highest levels of performance, system
integration and power management capability available for Pentium
PCI-based mobile systems.

***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.
