Setup Utility

Basic system information is maintained in the Setup Utility held in the system ROM, accessed 
by pressing the F10 key when prompted (on screen) during the boot sequence.

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.
