unconditional jump (JuMP) to the address that follows, like this:
JMP 0x89AB ; loads IP with the new value 0x89AB JMP 0xACDC:0x5578 ; loads CS with 0xACDC and IP with 0x5578 ; only works in real modeWe divide jump instructions into short jumps (one byte offset), near jumps (two byte offset?) long jumps (4bytes?) and far jumps (2 bytes segment / selector and full IP / EIP).JMP 0x56789AB1 ; loads IP with the value 0x56789AB1 ; only works in protected mode
