Execute Disable Bit: an Intel hardware-based protection against malicious code. It will detect the memory in which a
code can be executed or not. When enabled, it will prevent certain classes of malicious buffer overflow attacks when
combined with a supporting OS.
Hardware Prefetcher: when "Enabled", it will activate the mid level cache L2 streamer prefetcher.
Adjacent Cache Line P: it is the Adjacent Cache-Line Prefetch. When "Enabled", the CPU fetches Cache 1 & 2 for 128
bytes. If "Disabled", the CPU only fetches one cache for just 64 byte. The default is "Enabled".
