***Features
1.  Fully IBM PC/AT Compatible
2.  Flexible CPU and Local Bus Interface
    - Supports 80486SX/DX/DX2/DX4 and compatible CPUs
    - CPU speed up to 100 Mhz including 80486DX-50, 80486DX2-66 and 
      80486DX4-100
    - Supports CPUs with write-back internal cache, e.g. P24D, P24T 
      and Cx486DX/DX2
    - Snoop filtering for write-back CPUs
    - Supports SMI protocols of Intel, AMD, TI and Cyrix CPUs
    - CPU clock stretching and throttling
    - Zero frequency and zero voltage CPU suspend
    - Soft and hard CPU reset
    - Direct VESA and other local bus interface with DMA/master access
    - Built-in arbitration for two local bus masters
3.  Advanced Cache Controller
    - Write back/write through scheme
    - Direct map scheme
    - Flexible cache size: 0K/32K/64K/128K/256K/512K/1MB
    - One bank or two banks of data independent of cache size
    - Integrated 8-bit tag comparator
    - Interleaved SRAM access to achieve 2-1-1-1 burst fill
    - Supports burst read and burst write transfers
    - System and video BIOS cacheable and write-protect
    - Programmable cache timing
    - Programmable non-cacheable region
    - Optional combined tag and alter bit SRAM for the write-back 
      scheme
    - Eight bit tag under the combined tag-alter scheme without 
      sacrifice of cacheable space
4.  Fast Page Mode DRAM Controller
    - Mixed 256K/512K/1M/2M/4M/8M/16MxN DRAMs
    - 8 banks up to 128MB
    - Flexible column and row addresses
    - 30 pin (x9) and single/double density 72 pin (x36) SIMM 
      module support
    - Programmable DRAM timing
    - BIOS shadow at 16KB increment
    - 256/384K memory relocation
    - System management memory remapping
    - Decoupled DRAM refresh with staggered RAS timing
    - CAS-before-RAS and slow refresh
5. Synchronous ISA Bus Controller
    - Synchronous ISA bus clock
    - Programmable wait state, command delay and IO recovery time
    - Bus conversion and data alignment
    - Hardware and software de-turbo control
    - Fast reset and Gate A20 operation
    - Integrated 82C206 peripheral controller
    - Edge trigger or level sensitive interrupt controller
    - Flash EPROM and combined BIOS support
6. Integrated Power Management Unit
    - Normal, conserve, doze, sleep and suspend modes
    - System event monitoring with two event classes and two idle 
      timers
    - Primary and secondary interrupt differentiation for individual 
      channels
    - One extended peripheral timer and one general purpose timer
    - Automatic conserve mode operation for short and frequent system 
      idleness
    - Modular clock and modular power
    - CPU clock stretching, throttling or stop without affecting the 
      ISA bus clock
    - Zero frequency operation with automatic resume
    - Zero volt operation with leakage control
    - Four general purpose IO or power control ports
    - APM 1.1 compliant
7.  Integrated Local Bus IDE Controller
    - 32-bit host data transfer
    - Mode-3 transfer capabilities (>10MB/s)
    - Programmable read/write, master/slave and active/recovery timing 
      in units of CPU clock
    - Prefetch and write buffers
    - Support either primary (1F0-1F7h) or secondary (170-177h) 
      channel  with two devices
    - No external logic required
8.  High Integration and Complete Functionality
    - Glueless interface with the VT82C406MV IXP (Integrated X-bus 
      Peripheral Controller, 100PQFP) to eliminate the multi-clock 
      generator, the keyboard controller with PS2 mouse, the DS-1285 
      style real time clock with extended CMOS RAM and the address 
      buffers.
    - 9 TTLs for a complete main board implementation
    - Optional VT82C505 (160 PQFP) to bridge a VL/ISA system to the 
      PCI bus
9.  0.8um high speed and low power CMOS process
10. 208-pin PQFP package
