--- CMOS (Award) Password Introduction and Crack 0-3 * ---- When the computer is started, the CMOS data is transferred to the memory by the BIOS stored in the motherboard ROM to implement the control system. Among them, a small RAM on the Award Motherboard is used to store CMOS data, and addresses in a total of 128 bytes of 00-7F. The bytes 1c and 1D are stored in the CMOS password (ie Supervisor Password). It is of course that lithium battery in maintaining CMOS data survival. Port 70h, 71h is used to read and write to CMOS data.
0 - >> is not the party * 0-00 universal type is also the most bad: pull the battery or jumper (discharge)! ! --- A bird breaking system password? 1 - >> Crack party * 1 - Tveiling: Enter DOS, use Debug -o 70 10 -o 71 01 -q, you can directly enter CMOS, and No password asked. This party * is by writing a number to the CMOS chip, there is no * through its parity when it is turned on, so that the CMOS chip data is reset to the default factory value! ! !
Ugh. . . . ! ! ! It's hard, set the CMOS parameters, it is destroyed in Debug, 55555555555 ~~~~~ Don't cry, don't cry, look at the following two items *, everything is OK - >> * 2: Of course Programming, first declare: This program "*" is not what I have written, the original author Unkown Specific operation introduction is as follows: Outportb (0x70, i)
