**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.
