80386
i386
(Commonly abbreviated to "386", trademark
"Intel386") The successor to the Intel 80286
microprocessor. It was the first Intel processor with
32-bit data and address busses. It can address four
gigabytes (2^32 bytes) of memory; however, 16 megabytes is a
typical maximum in IBM PCs. The 386 allows multiple
application programs to run at the same time (when running
under 386-specific operating systems) using "{protected
mode}".
The first IBM compatible to use the 386 was the Compaq
386, before IBM used it in high-end models of their PS/2
series. It is also used in HP's RS series and many
others.
It does not require special EMS memory boards to expand
MS-DOS memory limits. With the 386, the EMS standard can be
simulated in normal extended memory, and many DOS add-ons
provide this "Expanded Memory Manager" feature.

intel 80386dx
(foldoc) | Intel 80386DX
A version of the Intel 80386 with a 32-bit {data
bus} and 32-bit address bus, a BGA. The 386DX was clocked
at 16 to 33 MHz by Intel and up to 40 MHz by AMD. It
comes in a BGA package.

386SX
A lower-speed version of the Intel 80386. It
uses a 16-bit data bus instead of a 32-bit data bus. It has a
24-bit address bus. It is faster than the 286, and more
importantly, like the full-size 386, provides more flexibility
in running existing DOS applications. Intel's version runs at
16 MHz, while AMD's can run at up to 33 MHz. It comes in a
PFP package.
