Hello Sinister Members,

As you know a couple of months back i Posted a thread with an issue i had of bypassing a BIOS Password/resetting it.

I would first like to Say Thank you to all the members that contributed on that thread for the major assistance i needed.

After tinkering with the computer and the web i manged to find my Current computer a lenovo Model, i looked deeper and found that my manufactured computer, had a Small Hole that is meant for emergency's/recovery purposes, Once pushed it turns on the computer and Boots on a Terminial That has Recovery commands. one of the commands had a BIOS Reset Option i Pressed it and it created a Prompt.

Many minutes later the Bios was reset, and that was it.

The prompt tab was secured, knowing so i had to reverse engineer the terminal to find the direct code.

And i found it, after that i posted Something about it on my thread a member pointed out a the specific code was while known And is a open source to the internet.

Here is the things i would Like to share:

debug
-o 70 10
-o 71 aa
-q




While playing Around again with the terminal i found this.

A Press Enter
MOV AX,0 Press Enter
MOV AX,CX Press Enter
OUT 70,AL Press Enter
MOV AX,0 Press Enter
OUT 71,AL Press Enter
INC CX Press Enter
CMP CX,100 Press Enter
JB 103 Press Enter
INT 20 Press Enter
Press Enter
G Press Enter
Q Press Enter

These are common Codes that you enter VIA Keyboard or input that could reset the passsword
Varying on you're system and the manufacturer

I would like to thank:

@Pikami @Synthx @mothered @Malvagio+ @gilmobiletech @Dr. Keter

And a Big thanks to @phyrrus9 For the images and a Brod explanation to what that was.
