WitrynaThe MOV instruction cannot be used to load the CS register. Attempting to do so results in an invalid opcode exception (#UD). To load the CS register, use the far JMP, CALL, or RET instruction. If the destination operand is a segment register (DS, ES, FS, GS, or SS), the source operand must be a valid segment selector. Witrynalanguages such as C and C++. Learning to program in assembly language is an excellent way to achieve this goal. Other PC assembly language books still teach how to program the 8086 processor that the original PC used in 1981! The 8086 processor only supported real mode. In this mode, any program may address any memory or …
