The Intel 80286 is the lower middle power microprocessor in the Intel lineup. It was originally designed as a completely new processor for the PC world, providing capabilities which were not allowed for in MSDOS. These capabilities include Virtual Memory Management, Memory over 640k bytes, as well as extended register sizes, and an extended instruction set.
