LMSW-Load machine status word (LMSW) is used to switch the 80286 from real mode to protected mode. The Intel 80286 (also marketed as the iAPX 286 and often called Intel 286) is a 16-bit microprocessor that was introduced on February 1, 1982. It was the first 8086 based CPU with separate, non-multiplexed address and data buses and also the first with memory management and wide protection abilities. 80286. 1GB of virtual memory. It has a MMU[memory management unit] It operates in 2 modes Real address mode Protected virtual address mode . Able to for example, one instruction can i) ends the current task ii) save its states iii) Register organization of 80286 The 80286 CPU contains the same set ofThese chapters provide detailed information on memory segmentation, registers, addressing modes and the general (application level) 80286 instruction set.
