9 bytes, clear the BIOS password.
The machine of the day before yesterday, I don't know who is locked, and no one stands out, because the BIOS is set to start from the C drive, and the C drive must format, I want to use a clean A: Pan to start, helpless From the modification of the BIOS. The chassis is really afraid of the battery clip. Fortunately, a colleague found a profile to say: Just write 11: Ff to 70:71 port. Take the test, really good These days I have made trials in other machines. Note: The following three methods are passed. Hello, what is good, please visit my homepage: http: // ware .51.Net This is a good way, so I recommend it to everyone. The following methods can be.
1) Directly call DEBUG. Enter::> Debug - O70, 11 - O71, FF then restart your computer, enter the BIOS and password?
2) Generate a kilobiospass.com, you can release your minimum software to everyone, it only has 11 bytes.:> Debug - n killbiospass.com - RCX CX 0000: B - A 1297: 0100 Push AX 1297: 010X Mov Al, 11 1297: 010X OUT 70, Al 1297: 010X MOV Al, FF 1297: 010X OUT 71, Al 1297: 010X POP AX 1297: 010X RET 1297: 010X - W This creates an executable file in the current directory : killbiospass.com, run it, then restart your computer, enter the BIOS and password? This file can only be 11 bytes, it should be the smallest tool! 3) Generate Delphi executable files, only 16k after compiling It is also small. Save the following to a killbiospass.dpr
Program killpass;
Begin ASM Push AX; MOV Al, $ 11; OUT $ 70, Al; MOV Al, $ FF; OUT $ 71, Al; Pop Ax; End; End. Compiled.
