7. Enter the password again in the Enter New Password Again field. If you forget this password, the drive will be rendered permanently disabled. 8. Select File > Save Changes and Exit and press the F10 key. After you press the F10 key, the system does a "cold boot" before invoking the DriveLock function. NOTE: This process can also be used to set the DriveLock Master password by selecting Master in Step 5. When the unit "cold boots," you will be prompted to enter the DriveLock password for each DriveLockcapable drive for which you have previously set a password. You have two chances to entire the password correctly. If the correct password is not entered correctly, the unit will attempt to boot anyway, but the boot process will most likely fail as data from an unlocked drive cannot be accessed. In a single drive system, if the drive is drive-locked, then the system will most likely not boot to the operating system. The system may try to boot from the network instead, depending on the boot ordering options. Regardless, the drive-locked drive remains inaccessible without the DriveLock password. In a two drive system where there is a boot drive and a data drive, one can apply the DriveLock feature only to the data drive. In this case, the unit can always boot, but the data drive is accessible only when the DriveLock password is known. Any cold boot requires you to enter DriveLock passwords. But DriveLock passwords are required for warm boots as well. For example, if you booted to DOS and entered Ctrl-Alt-Del, you would need to enter the DriveLock password before the unit will complete the next boot cycle. This warm boot behavior is consistent with the DriveLock feature found on IDE hard drives. Hood sensor (smart cover sensor) The optional hood sensor is a combination of hardware and software technology that can alert you when the workstation side access panel has been removed if the sensor has been properly configured in the Computer Setup Utility. There are three levels of protection, as described in the following table. Table 3-5 Hood Sensor Protection Levels Level Setting Description Level 0 Disabled Hood sensor is disabled (default). Level 1 Notify User When the workstation restarts, the screen displays a message indicating that the workstation side access panel has been removed. Level 2 Setup Password When the workstation is restarted, the screen displays a message indicating that the workstation side access panel has been removed. You must enter the setup password to continue. These settings can be changed using the Computer Setup (F10) Utility. Setting the hood sensor protection level 1. Power on or restart the workstation. 2. As soon as the workstation is powered on, press and hold the F10 key until you enter the Computer Setup (F10) Utility. Press Enter to bypass the title screen, if necessary. NOTE: If you do not press the F10 key at the appropriate time, you must restart the computer and press and hold the F10 key again to access the utility. If you are using a PS2 keyboard, you might see a Keyboard Error message-disregard it. 46 Chapter 3 System management ENWW

Hood sensor (smart cover sensor)

The optional hood sensor is a combination of hardware and software technology that can alert you when

When the workstation is restarted, the screen displays

a message indicating that the workstation side access

panel has been removed. You must enter the setup

password to continue.

These settings can be changed using the Computer Setup (F10) Utility.

Setting the hood sensor protection level
