Note: Do not try to attempt to write registers values on the screen using ASM for now, try something easier like hello world program that asks for a keyboard input, and then it will echo back with the string

What assembler are you using?
). 
If you would use BIOS, MS-BOSS wouldn't have idea that the INT0 has changed... Its quite simple, but harder to tell -> if you MOVe something to a register, it will automatically erase everything that is stored on the destination (register), and replace it with contents specified as the second operand (source, in the INTEL syntax). But if you have some high number stored in EDX (full 32bit number, like 0FFFFFFFFh), and you would just do MOV DX, 5, I think the CPU will leave the 32bit part "as it is"... Correct me if this is wrong please.), or 0x0 = 0 simply. Save two bytes of "0x" in your asm code , so if CMP EDX,0 ; JNE NOTPRIME would jump to label NOTPRIME if EDX is not 0. I think you already know that ))...and DX should hold the remainderyes, and bx should hold the remainder right? = 0;
