Currently I am running the AMD 64 X2 Dual Core Processor 5000+ with Windows Vista. I am new to assembly but have been reading a book on it for a while and am coming to grasps with how it works. The problem is, the book I am reading is from the 1980s and the processor is the Intel 8088 series. What it looks like is registers, flags, and neumonics have been added along with more bits in a byte. Is there anything else that has been added to the new processors that is not in the 8088 series? What is different in the AMD processors then in the Intel? Where could I "update" my knowledge of Assembly.
