***Notes:...
***Info:
The OPTi  design team  is proud to  present the 32-bit  486/Pentium AT
solution with  VESA Local bus. As  always, the product  emphasis is on
value.  The OPTi 82C571/572 chipset  is crafted to provide the highest
performance   but   most   cost-effective  system   solution   without
compromising quality, compatibility or reliability.

The 82C571/572 is a top-of-the-line solution for the server/power user
market. Flexibility of design without using the most expensive support
parts has  been given  key importance. This  ensures the  total system
cost to be  at the high-end 486 level - and  with upgradability to the
high-end Pentium performance.

The 82C571/572 has a state-of-the-art  cache controller for up to 2 MB
of Write-back cache support.  The DRAM controller also supports posted
writes  for faster performance  on write  cycles. The  OPTi 82C571/572
provides 486 PC power users the horsepower of the 64-bit Pentium at 60
MHz and 66 MHz as needed in the future.
