**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.

**82489DX Advanced Programmable Interrupt Controller 10/12/92
***Notes:...
***Info:
1.0 INTRODUCTION
The 82489DX Advanced Programmable Interrupt Controller provides
multiprocessor interrupt management, providing both static and dynamic
symmetrical interrupt distribution across all processors.
The main function of the 82489DX is to provide interrupt management
across all processors. This dynamic interrupt distribution includes
routing of the interrupt to the lowest-priority processor. The 82489DX
works in systems with multiple I/O subsystems, where each subsystem
can have its own set of interrupts. This chip also provides
inter-processor interrupts, allowing any processor to interrupt any
processor or set of processor. Each 82489DX I/O init interrupt input
pin is individually programmable by software as either edge or level
triggered. The interrupt vector and interrupt steering information an
be specified per pin. A 32-bit wide timer is provided that can be
programmed to interrupt the local processor. the timer can be used as
a counter to provide a time base to software running on the processor,
or to generate time slice interrupts locally to that processor. the
82489DX provides 32-bit software access to its internal
registers. Since no 82489DX register read have any side effects, the
82489DX registers can be aliased to a user read-only page for fast
user access (e.g., performance monitoring timers).
The 82489DX supports a generalized naming/addressing scheme that can
be tailored by software to fit a variety of system architectures and
usage models. It also supports 8259A compatibility by becoming
virtually transparent with regard to an externally connected 8259A
style controller, making the 8259A visible to software.
