**Definition of a chip set:
In short it is a set of chips that allow a system designer to build a
computer. If we restrict the term 'chip' to that of a microchip then
technically any microcomputer contains a chip set, even one based of
7400-series logic alone.
In the context of this document, a chip set is defined as any group of
chips used to implement an IBM or IBM-compatible PC/XT/AT/386/486/etc
system.
There are 2 main categories that these chips fall into:
1. Direct copies or re-implementations of Intel chips
2. Chip sets sold as a set of chips to implement an IBM-compatible
that differ in some way to those used in an IBM system, e.g. not
pin compatible.
An example of the former would be some early chips built by VLSI
Technology (at the time known as VTI, to implement a 286:
o VL82C37A is a: 82C37A DMA controller
o VL82C59A is a: 82C59A interrupt controller
o VL82C54A is a: 82C54 timer
o VL82C612 is a: 74LS612 memory mapper
o VL82C84A is a: 82284 clock generator and ready interface
o VL82C88 is a: 82288 bus controller
These are all direct replacements for the parts used in an IBM AT.
Many companies had compatible versions of these chips.
An early example of the latter is the Chips & Technology NEAT chip set:
o 82C211 CPU/Bus controller,
o 82C212 Page/Interleave and EMS Memory controller,
o 82C215 Data/Address buffer
o 82C206 Integrated Peripherals Controller (IPC).
The description does not map directly to the parts used in the IBM AT.
Later chip sets are often even more integrated sometimes consisting of
just one chip, although two seems to be the most common.
The latter is generally considered the definition of a chip set, and
the former is not generally considered a chip set per-se. However when
looking at the early chip sets this distinction can be very
slight. Because of this, sets of chips meeting the criteria for (1.)
have been included where possible.

***Notes:...
***Info:
The 82498 Cache Controller and multiple 82493 Cache SRAMs combine with
the Pentium processor (735/90, 815/100) and future Pentium Processors
to form a CPU Cache chip set designed for high performance servers and
function-rich desktops. The high-speed interconnect between the CPU
and cache components has been optimized to provide zero-wait state
operation. This CPU Cache chip set is fully compatible with existing
software, and has new data integrity features for mission critical
applications.
The 82498 Cache Controller implements the MESI write-back protocol for
full multiprocessing support. Dual ported buffers and registers allow
the 82498 to concurrently handle CPU bus, memory bus, and internal
cache operation for maximum performance.
The 82493 is a customized high-performance SRAM that supports 64-, and
128-bit wide memory bus widths, 32-, and 64-byte line sizes, and
optional sectoring. The data path between the CPU bus and memory bus
is separated by the 82493, allowing the CPU bus to handshake
synchronously, asynchronously, or with a strobed protocol, and
allowing concurrent CPU bus and memory bus operations.
