Hello, I am reading programmin ground up book on assembly langauge and I have a doubt,which I am unable to pass. The first program in chapter 3 in which we just exit, I found that inserting tha max 32bit value in the %ebx register and it is replying 255 instead of the maximum value(4294967296), when I enter the 'echo $?' Command in terminal. Plz clear my doubt why it is repliying different number.
