initial jump

Assuming you read the binary file (without running a disassembler)
Here are the possible jump instructions:

Code:

EB cb JMP rel8 7+m Jump short E9 cw JMP rel16 7+m Jump near, displacement relative to next instruction FF /4 JMP r/m16 7+m/10+m Jump near indirect EA cd JMP ptr16:16 12+m,pm=27+m Jump intersegment, 4-byte immediate address EA cd JMP ptr16:16 pm=45+m Jump to call gate, same privilege EA cd JMP ptr16:16 ts Jump via task state segment EA cd JMP ptr16:16 ts Jump via task gate FF /5 JMP m16:16 43+m,pm=31+m Jump r/m16:16 indirect and intersegment FF /5 JMP m16:16 pm=49+m Jump to call gate, same privilege FF /5 JMP m16:16 5 + ts Jump via task state segment FF /5 JMP m16:16 5 + ts Jump via task gate E9 cd JMP rel32 7+m Jump near, displacement relative to next instruction FF /4 JMP r/m32 7+m,10+m Jump near, indirect EA cp JMP ptr16:32 12+m,pm=27+m Jump intersegment, 6-byte immediate address EA cp JMP ptr16:32 pm=45+m Jump to call gate, same privilege EA cp JMP ptr16:32 ts Jump via task state segment EA cp JMP ptr16:32 ts Jump via task gate FF /5 JMP m16:32 43+m,pm=31+m Jump intersegment, address at r/m dword FF /5 JMP m16:32 pm=49+m Jump to call gate, same privilege FF /5 JMP m16:32 5 + ts Jump via task state segment FF /5 JMP m16:32 5 + ts Jump via task gate
