What is the boot code?

1. When the boot time in general, press the "Delete" key, enter the CMOS settings interface.

2. Use the arrow keys to select "Set Supervisor Password" and press the ENTER key.

3. Type the password, press ENTER, type the password again, and press ENTER. 4. Press the F10 key to save and exit.

In most cases, the default setting for "Security Option" is "system", meaning that a password is required to enter the system, and a password is required to enter the CMOS settings when set to Setup. The friend's computer is set to "Setup", so it will not be valid until the password is started.
