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  has been sourced  from the
second.

Difference to 82497/492 is this supports 1 Mbyte to 2 Mbyte cache.

**82C499         DXSC DX System Controller                        c:93
***Info:
The  OPTi  82C499 provides  a  highly  integrated  solution for  fully
compatible, high-performance  PC/AT platforms. This  chip will support
the  Intel  486SX/DX/DX2/487SX,   Intel  386DX  and  IBM/Cyrix  486DLC
microprocessors in the most cost effective and power efficient designs
available today.  Since  the device is so critical  to the performance
and cost structure  of a PC, this highly  integrated approach provides
the foundation for a very cost effective platform without compromising
performance.  For  power users,  this chip offers  optimum performance
for  systems  running up  to  50MHz. The  OPTi  DXSC  chip provides  a
solution  positioned  to deliver  value,  without neglecting  quality,
compatibility, or reliability.

The  82C499 integrates  a write-back  cache controller,  a  local DRAM
controller,  an integrated  peripherals controller  (82C206),  the CPU
state machine,  the AT bus  state machine, and  data buffers all  in a
single 208-pin PFP.  New on-chip hardware provides the  hooks for OPTi
and VESA local bus device support.
