BIOS Setting Password
The option description:
Gives the chance to install, change or remove the password for access to options BIOS Setup. If it is necessary to install the password, select this point, enter the password, and then, in an additional window, repeat password entry. Thus, it is guaranteed that you are not mistaken. At change it is necessary to enter in the beginning the old password, and then to specify new, entering it twice. At removal of the password you should push [<Enter>] instead of input new.
The password can consist only of letters of the English alphabet, and the upper and lower registers do not differ, and digits. The maximum length of the password — eight characters.
