***Notes:...
***Info:
The  OPTi Python  Chipset provides  a highly  integrated  solution for
fully  compatible, high-performance  PC/AT  platforms. Together,  with
OPTi's  82C206 Integrated  Peripheral Controller  (IPC),  this chipset
will  support the  Pentium processor  in the  most cost  effective and
feature-rich designs available  today. This highly integrated approach
provides  the  foundation  for   a  cost  effective  platform  without
compromising performance. The OPTi  Python Chipset supplies a powerful
solution  positioned  to  deliver  value without  neglecting  quality,
compatibility, or reliability.

The  Python Chipset  is  comprised  of two  chips,  the 82C547  System
Controller (SYSC) and  the 82C546 AT Bus Controller  (ATC). A complete
Pentium  processor solution  consists of  the Python  Chipset  and the
82C206 Integrated Peripheral Controller (IPC).

82C546 (ATC) AT Bus Controller
The 82C546  ATC integrates the AT  bus interface and  data buffers for
transfers between the  CPU data bus, local data bus  and the DRAM data
bus. It also provides the ISA to local bus command translation.

o 208-pin PQFP
o Data bus buffer (host data to memory data)
o Data bus buffer control (ISA to memory)
o Parity generation and detection circuitry
o Keyboard controller chip select
o Local bus interface (ISA to local bus command translation)

82C547 (SYSC) System Controller
The  82C547 SYSC  provides  the  control functions  for  the host  CPU
interface, the  32-bit local  bus interface, the  64-bit Level  2 (12)
cache and  the 64-bit DRAM bus.  The SYSC also controls  the data flow
between the CPU bus, the DRAM bus, the local bus, and the 8/16-bit ISA
bus.

o 160-pin PQFP
o Pentium CPU interface
o DRAM controller
o L2 cache controller
o Ll cache controller
o Local bus interface
o Reset generation
o Arbitration logic
o Data bus buffer control (memory data to/from host data)
o Extended DMA page register
o Keyboard emulation of A20M# and CPU warm reset
o Port B and Port 92h Register

82C206 (IPC) Integrated Peripherals Controller
The 82C206  IPC provides two  DMA controllers, two  interrupt control-
lers, one timer/counter, and a real-time clock in an industry standard
single-chip  solution  for  the  peripherals  attached  to  the  PC/AT
peripheral bus.

o 84-pin PLCC or 100-pin PQFP
o Supports four DMA transfer modes
o Special Commands provided for ease of programming

Support Chips
The  82C606A and 82C606B  are two  buffer/translation devices  used to
translate  3.3V signals to  5.0V signal  levels in  Python motherboard
solutions. These devices buffer the CPU  address bus to the ISA and VL
address buses, the  82C546 ATC's memory data bus to  the ISA data bus,
the peripheral  XD bus  to the ISA  SA and  SD buses. The  82C606A and
82C606B integrate  a number of  glue logic TTL  devices (approximately
eleven), hence  reducing the  amount of TTL  on the  motherboard.  The
82C606A  and 82C606B  devices are  actually the  same device  with two
strapping options. Pulling the CONFI/2#  pin high causes the device to
function in the 82C606A Mode.  Pulling the CONFII2# pin low configures
the device to function in the 82C606B Mode of operation.

o 100-pin PQFP
o Mixed voltage to support 3.3V to 5.0V signal translation
o Two devices replace approximately eleven TTL devices

**W83759/A/F/AF   Advanced VL-IDE Disk Controller                  <96
***Notes:...
***Info:
GENERAL DESCRIPTION

The  W83759A  is  an  advanced  version of  Winbond's  popular  VL-IDE
interface chip,  the W83759. The  W83759A retains all of  the features
and  compatibility of  the W83759  (the chip  meets the  ANSI  ATA 4.0
specification  for IDE  hard disk  operation and  the VESA  VL-Bus 2.0
specification  for  PC  local  bus devices)  while  incorporating  new
features  to   meet  Enhanced  IDE,  SFF-8011,   ATA-2,  and  Fast-ATA
specifications.

Supports Disk Capacity of Greater than 528 MB
The W83759A's  driver can handle remapping  from BIOS CHS  mode to HDD
LBA mode.  This scheme  enables users  to break the  528 MB  per drive
barrier, allowing  full use  of BIOS INT13  CHS information  in drives
with a capacity of up to 8.4 GB.

High Speed Host Transfer Rate
The W83759A supports  Enhanced IDE PIO mode 3 and Fast  ATA PIO mode 3
and 4  timing; jumper  settings or driver  programming can be  used to
select  the PIO  mode  and a  33  or 50  MHz  VL-Bus clock.  Different
programming timing  can be selected  for different drives in  the same
system. The burst transfer rate is shown in the following table.

ATA PIO  IDE COMMAND CYCLE  BURST TRANSFER RATE  IORDY THROTTLE 
MODE     TIME (nS)          (MB/sec)             CONTROL
0 	 600  		    3.33 		 Option
1 	 383 		    5.22 		 Option
2 	 240 		    8.33 		 Option
3 	 180 		    11.1 		 Required
4 	 120 		    16.6		 Required

Dual IDE Channels
Like  the  W83759,  the  W83759A  supports  a  secondary  IDE  address
(170h-177h/376h)  and  IRQ15  for  applications with  four  hard  disk
drives.  Additionally,  the  primary  and secondary  channels  can  be
independently  enabled  or disabled  by  jumper  settings or  software
programming.

Non-disk IDE Peripherals
Because  the command  cycle can  be programmed  individually  for each
drive and  dual IDE channels  are supported, non-disk  IDE peripherals
(such  as an  ATAPI  CD-ROM or  tape  drive) can  be  attached to  the
secondary  IDE without  affecting the  transfer rate  of the  ATA disk
drive.  Sales of ATAPI  IDE CD-ROMs  are expected  to grow  rapidly as
these devices become a standard part of many users' desktop PC setup.

The W83759A provides all  of the next-generation ATA-IDE requirements,
including  support for  high  capacity disk  drives,  high speed  host
transfers, multiple IDE peripherals,  and non-disk IDE peripherals. It
makes high-performance, low-cost, easy-to-use IDE machines possible.

The  W83759A is  pin-to-pin backward  compatible with  the  W83759. In
addition  to  the  advanced  features  described  above,  the  W83759A
supports  automatic   power-down,  standby,  and   suspend  APM  power
management states for green PC applications. This new chip is packaged
in a 100-pin QFP.

The table below compares the W83759 and W83759A:
