4. Write an instruction sequence to configure the 80386DX as follows: interrupts not accepted; save the original contents of flags SF, ZF, AF, PF, and CF at address BODOH and then set CF. 5. Identify the type of jump, the type of operand, and operation performed by each of the following instructions. If the state of the 80386DX is as follows before executing each instruction, to what address is program control passed? CS=1075H, IP=0300H, EBX=00000102, ESI=09000100H, DS:100H=00H, DS:101H=10H, DS:102H=20H and DS:103H=40H. a) JNP 1000H b) JMP DWORD PTR[100H] c) JMP ESI d) JO WORD PTR [BX]
