BIOS security is system protection that can prevent authorized users from modifying your CMOS and unauthorized users from accessing your workstations. To help prevent an authorized person from changing a workstation's CMOS settings, use the BIOS to create a supervisor password that limits access to the workstation. To prevent an intruder from accessing your system by using software started from the A:/ drive, use the BIOS to lock the boot sequence so that the workstation starts only from the C:/ drive. Refer to your Dell documentation for details on how to configure the BIOS.
Although it is not part of DeltaV security, Emerson recommends that you use BIOS security to avoid unauthorized tampering on your workstations.
