System Setup and Boot

Basic system information regarding file, storage, security, and power configuration is maintained in the Setup Utility held in the system ROM. The Setup Utility is accessed by pressing the F10 key as soon as the computer is turned on. If the screen prompt opportunity is missed, a restart will be necessary.

Note: Not all features are available on all models.

Failsafe Boot Block ROM

The Boot Block is a flash-protected section of the ROM that contains code that checks for a valid system BIOS image when the system is turned on.

- If the system BIOS image is valid, the system starts normally.

- If the system BIOS image is not valid, a failsafe Boot Block BIOS provides enough support to:

- search remopvable media for BIOS image files. If an appropriate BIOS image is found, it is automatically flashed into the ROM.

- start the system from bootable removable media that automaticaly invokes system

BIOS upgrade utilities. When an invalid system BIOS image is detected, the system power LED will blink red 8 times, one blink every second. Simultaneously, the speaker will beep 8 times. If the portion of the system ROM containing the video option ROM image is not corrupt, “Boot Block Emergency Recovery Mode” will be displayed on the screen. To recover the system after it enters Boot Block Emergency Recovery Mode, complete the following steps:

1. Remove all removable media removable storage options.

2. Turn off the power.

3. Insert a diskette, CD, or USB flash device containing the desired BIOS image file in the root directory. Note: The media must be formatted using the FAT 12, FAT 16, or FAT 32 file system.

4. Turn on power to the system. If no appropriate BIOS image is found, the failsafe Boot Block BIOS will attempt to start the system from a bootable device. If no bootable device is found, you will be prompted to insert media containing a BIOS image file or BIOS upgrade utility. If the system successfully reprograms the ROM, the system will automatically restart.

Security Functions

The system offers independent Power-On and Setup passwords for system and data protection. The Power-On password protects the computer from unauthorized access by prompting the user for a password during power up. The Setup password protects the computer from unauthorized or inadvertent re-configuration of legacy device resource settings or ROM flash upgrade by prompting the user for a password prior to entering the Setup Utility.

To establish a password:

1. Turn on or restart the computer. If you are in Windows, click Start > Shut Down >

Restart the computer.

Security Functions (Continued)

2. As soon as the computer is turned on, press and hold F10 until you enter Computer Setup. Press Enter to bypass the title screen, if necessary. If you do not press F10 as soon as the computer starts, a restart will be necessary.

3. Select Security, then select Setup Password or Power-On Password and follow the instructions on the screen.

Before exiting, click File > Save Changes and Exit.

To change a Power-On or Setup password:

1. Turn on or restart the computer. If you are in Windows, click Start > Shut Down > Restart the Computer. Run Computer Setup (F10).

When the key icon appears, type your current password, a slash (/) or alternate delimiter character, your new password, another slash (/) or alternate delimiter character, and your new password again as shown:

current password/new password/new password.

NOTE: Type the new password carefully since the actual characters do not appear on the screen.

2. Press the enter key.

The new password will take effect the next time the computer is restarted.

To delete a password using Setup:

1. Turn on or restart the computer. If you are in Windows, click Start > Shut Down > Restart the Computer. To delete the setup password, run Computer Setup (F10).

2. When the key icon appears, type your current password followed by a slash (/) or alternate delimiter character as shown. Example: currentpassword/

3. Press the Enter key.

To delete or disable the Power On and Setup passwords:

1. Shut down (Power down) the system and disconnect the power cord from the outlet or the system unit.

2. Remove the chassis cover.

3. On the system board, remove the jumper on pins 1 and 2 of header E49 and place only on pin 2.

4. Replace the chassis cover and reconnect the power cord.

NOTE: Setup password may be used in place of Power-on password to boot system.
