(Commonly aBBreviated to "386", trademark "Intel386") The successor to the Intel 80286microprocessor. 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. See also Intel 80386SX, BSD386. (1995-02-21)
