About CMOS password crack and principles Our nature is destroy !!!! .................... Haha, sorry, lost. My name is a sweet and sorcer, I'm going to break the class today, I really don't hate the destruction, because we have to prevent everything from existence, first of all, is an annoying CMOS password. Although there are many articles to introduce this knowledge, I still want to introduce some things and principles that have different destruction. First introduce CMOS, if you are not interested, you can sleep. After my efforts, I finally found 128 bytes of CMOS (I checked me a day): 00 ~~ 09 System clock 0A ~~ 0D register status 0e diagnostic state (don't know what it means) 0f State (don't know what it means) 10 flop drive type 11 Cipher / reservation (still unclear what) 12 hard disk type 14 device byte 15 ~ ~ 18 memory (basic, expansion) 19 ~~ 1A hard disk parameter 2e ~~ 2F school Inspection and (very important, useful !!) 30 ~ ~ 31 expansion memory 32th century 33 mark code 38 ~ ~ 3B password storage area (key stuff!) Nothing mentioned is a reservation byte. Let's talk about the most basic crack method and principles: Debug -o 70 10 -O 71 11 -Q This is the most widely cracking method, the cracked rate is 99.609375%, this number is not Hu Yu's &
