**Spelling errors/mistyped words
Yes, I know there are spelling errors, and things are mistyped. It
seems no matter how hard I try my fingers hit 't' twice when typing
'compatible' rendering it 'compattible' numerous, (thousands actually)
times. I don't have the time or the will to check the spelling of
everything. Basic spell checking has been peformed. Please let me know
if there is anything that would lead to incorrect information, or
something is so mangled that it needs revising. But if you can
basically understand what was intended, just cope with it. Just
cope:-)
BTW, "110" port is an "I/O" port that has been OCRed badly, as is an
"1/0" port.

**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.
