China DOS Union

If the machine can boot into DOS or Windows, you can try to clear the CMOS according to the following steps:
C:\>DEBUG
-o 70 11
-o 71 ff
-q

1)、o 70 2E
o 71 0
2)、o 70 16
o 71 16
3)、o 70 FF
o 71 17
4)、o 70 10
o 71 0
5)、o 70 11
o 71 FF

Can't see it?

Why do I need to reply?

Did you get tricked by Playboy2925 again? Below Playboy2925 is just a signature, with nothing else. Please refer to the relevant topics in the Water Cooler forum.

Hehe!! If what the master said is correct, Playboy2925 is kidding. I also fell for this before

You can also use this software to clear the CMOS

But it seems that after removing the password, it doesn't work when setting it up again. What should I do?

And after setting a password in CMOS, there's simply no way to enter DOS or Windows. It seems it can only be tested on my own computer, hehehe!

Do you clear it with debug or with the software I uploaded?

If in the COMS only the hard disk boot is set or the super password is forgotten, and you can't enter DOS at all, can this method still be used? Please experts give advice! Thank you!

If it's not to clear the CMOS password but just to find out what the CMOS password is, then how should it be done?

Forgot the CMOS password, can't enter DOS at all!
Haha! By the way,
However, there is still a use for the DOS (or WIN) program to crack the CMOS password:
On the machine where a friend set the CMOS password, after he turns on the computer, pretend to say to play with the computer
Then, haha! Here comes your chance!
You can use my program (only cracks, doesn't damage, no harm to the computer at all)
After running, it immediately displays the enterable CMOS password (may not be the original one)
......
Haha! When the friend is away, his beloved computer will be yours!
