Select Security tab from the ARK-2250R main BIOS setup menu. All security setup
options, such as password protection are described in this section. To access the sub
menu for the following items, select the item and press <Enter>:
Change Administrator / User Password : Select this option and press Enter to
access the sub menu, and then type in the password.
The password length is Minimum 3 digits and maximum 20 digits.
If you set "Administrator Password" only, it will require a password only when enter-
ing the BIOS setup.
If you set "User Password" only, it will require a password every boot-up. However, if
the Administrator password is not set, using "User Password" to enter the BIOS
setup will permit all access privileges.
If you set both passwords, it will require a password every boot-up. To boot into the
OS, you can use either password. To enter BIOS setup, "Administrator Password"
gives all privileges to access all items, while "User Password" only gives partial privi-
leges.
