***Info:...
***Configurations:...
***Features:
o   Low cost, low power, CMOS Technology
o   Supports 386DX, 486 DX/DX2/SX CPUs as well as Intel
    P24T and Cyrix Cx486S/S2 and Cx486DX/DX2 CPUs
o   One 160-pin CMOS Plastic Flat Package (PFP), one 84
    pin PLCC (or one 100-pin PFP)
o   Internal buffers and termination to reduce external parts count
o   Copy-Back Direct-Mapped Cache: 32/64/128/256KB for 386, and 
    64/128/256/512KB for 486
o   Up to 10% performance enhancement from write-through cache scheme
o   Supports 2-1-1-1 or 3-2-2-2 cache cycles
o   On-chip comparator determines cache hit/miss
o   Up to 64MB of local high-speed, page mode DRAM memory space
o   Burst line fill during cache read-miss
o   Control of one non-cacheable region
o   Shadow RAM support for system, video and adapter card BIOS
o   Optional caching of shadowed video BIOS
o   Hidden refresh support to enhance system performance
o   Turbo/slow speed selection (386 mode only)
o   AT bus clock selectable from CLKI (/6, /5 /4, /3)
o   CAS-before-RAS refresh reduces power consumption
o   Optional 0 or one wait state for cache write-hit
o   387 coprocessor support for 386 mode
o   Internal CD and CA bus pull-up resistors to save components and 
    board real-estate
o   Comprehensive VL bus and OPTi high-performance local bus support
o   On-chip hardware provides direct support for up to two
    VL bus master devices
