System Setup and Boot
Basic system information regarding file, storage, security, and power configuration is main-
tained 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 sys-
tem 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.
