Password Design Description
Password Design Overview
The owner of the system has the option to limit access to the system. The system
limits access by requiring the user to enter a password. There are three categories
of restricted access.
The first category is power-on. If this category is enabled, the system will prompt the
user to enter the Power-On password (POP) when the system is powered on. The
user must supply the Power-On password.
The second category is privileged access. Privileged access is needed to perform
functions on the SMS, or boot from a device that isn't in the boot path. When the
user attempts to do one of these things, the system will prompt for the Privileged
Access Password (PAP). The user must supply the PAP.
The third category is unattended start mode. In unattended start mode, the system
will boot from a defined boot device, but the keyboard will be locked until the user
enters the Power-On password.
Enabling Security
Utilities are provided to allow the system owner to enable any of the above security
modes and to enter or change the Power-On or Privileged-Access passwords. The
passwords can be up to 8 characters long. After entering a password, the user is
prompted to verify it by entering it a second time. After the password has been
entered two consecutive times, it is saved in CMOS.
Storing of Password
The POP and PAP are stored in CMOS. The time that each password was saved,
and the time that each password is read is also stored. If for any reason the
contents of CMOS are suspect (bad battery or CRC), the passwords will be
considered valid, but unusable. The areas in CMOS that contain the password are
locked before the operating system is booted. After the passwords have been
locked, the user must power off the system before the passwords can be accessed
again.
