**82c496A/B      DXBB PC/AT Chipset                             <Mar92
***Notes:...
***Info:...
***Configurations:...
***Features:
o   Modular design is simplified by using the same chipset for 386DX. 
    486SX, 486DX and 487SX systems
o   One 184-pin CMOS Plastic Flat Package (PFP), and one 84-pin PLCC
o   Supports 3,2,2,2 cache DRAM burst cycles for 486 based system
o   Supports up to 64-MB of high speed local memory
o   Supports 256K, 1M and 4 M DRAM with two-way page mode operation
o   Provides programmable control of two non-cacheable regions
o   Shadow RAMs support
o   Optional caching of shadowed Video BIOS
o   Transparent 8042 keyboard emulation for Fast CPU reset and GATEA20 
    generation
o   Hardware support for Turbo mode
o   Selectable AT bus clock of CLK2IN/4, CLK2IN/5, CLK2IN/6 or 
    CLK2IN/8
o   0 or 1 wait state options for 16-bit AT bus cycles
o   Slow refresh available for laptop applications
o   Hidden refresh to boost CPU bandwidth
o   CAS# before RAS# refresh reduces power consumption
o   WEITEK 3167/4167 coprocessor support
o   High performance local bus device support

***Notes:
The information in this entry is from the brochure, not a datasheet.

This chipset is designed for  Pentium 60/66Mhz system with an EISA bus
the datasheet  does not mention support  for VESA local  or PCI buses.
But  every other  source found  states it  supports VLB.  It  may also
support dual CPUs.
