Boot Block Emergency Recovery Mode

failure. For example, if a power failure were to occur during a BIOS upgrade, the ROM flash would be incomplete. This would render the system BIOS unusable. 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 removable media for BIOS image files. If an appropriate BIOS image file is found, it is automatically flashed into the ROM.

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.Turn off the computer.

2.Insert a flash drive or CD containing the BIOS image in the root directory. The media must be formatted using the FAT12, FAT16, or FAT32 file system.

3.Turn on the computer. If no appropriate BIOS image is found, you will be prompted to insert media containing a BIOS image file. The system will automatically flash the ROM. After a successful flash, the system will either automatically restart or prompt the user to unplug the unit, wait 5 seconds, reattach the power cord, and then press the power button.

4.Remove the removable media used to upgrade the BIOS.

5.Turn the power on to restart the computer.

NOTE: BitLocker prevents Windows Vista from booting when a CD containing the BIOS image file is in an optical drive. If BitLocker is enabled, remove this CD before attempting to boot to Windows Vista.

Password Security

Establishing a Setup password using computer setup

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

2.As soon as the computer is turned on, press F10 when the monitor light turns green to enter Computer Setup. Press Enter to bypass the title screen, if necessary. If you do not press F10 when prompted, a restart will be necessary.

3.Select Security > Setup Password and follow the instructions on the screen.

4.Before exiting, click File > Save Changes and Exit.

Changing a Power-on or Setup password

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

2.If you want to change the Setup password, as soon as the computer is turned on, press F10 when the monitor light turns green to enter Computer Setup. Press Enter to bypass the title screen, if necessary.

3.If you want to change the Power-On password, 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 characters do not appear on the screen.

4.Press Enter.

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

Deleting a Power-on or Setup password

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

2.To delete the Setup password, as soon as the computer is turned on, press F10 when the monitor light turns green to enter Computer Setup. Press Enter to bypass the title screen, if necessary.

3.To delete the Power-on password, when the key icon appears, type the current password followed by a slash (/) or alternate delimiter character as shown: currentpassword/

4.Press Enter.

Clearing CMOS

1.Turn off the computer and any external devices, and disconnect the power cord from the power outlet.

2.Remove the access panel.

3.On the system board, press and hold the CMOS button for 5 seconds.

4.Replace the access panel, external devices, and reconnect the power cord.

5.Turn on the computer.

You will receive POST error messages after clearing CMOS and rebooting advising you that configuration changes have occurred. Use Computer Setup to reset any special system setups along with the date and time.
