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: Diagnostic functions are provided by the Setup Utility (in system ROM) and by HP Insight Diagnostics. The HP Insight Diagnostics utility allows you to view information about the hardware configuration of the computer and perform hardware diagnostic tests on the subsystems of the computer. The utility simplifies the process of effectively identifying, diagnosing, and isolating hardware issues. Boot Block Recovery 7. Select HP Insight Diagnostics Offline Edition. Insight Diagnostics may be downloaded from the HP Web site using the following procedure: 1. Go to www.hp.com 2. Click the Software & Download driver link. 3. Enter the product number (for example, dc7500) in the text box and press the Enter key. 4. Select the specific product. 5. Select the OS. 6. Click the Diagnostics link. 8. Click Download. 1. Remove any bootable media from the computer and turn off power. NOTE: The download includes instructions on how to create a bootable CD. 2. Insert a USB flash device or CD containing the BIOS image file in the root directory. The media must be formatted using the FAT12, FAT16, or FAT32 file system. Clearing CMOS 3. Turn on power to the system. 4. The system automatically reprograms the ROM. 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. 1. Turn off the computer and any external devices, and disconnect the power cord from the power outlet. 2. Remove the chassis access panel. 3. Locate the jumper labeled E69. 4. Remove the blue CMOS jumper from pins 4 and 6 and put the jumper on pins 2 and 4. This clears CMOS. Password Security If the system is equipped with an embedded security device, refer to the HP ProtectTools Security Manager Guide at http://www.hp.com. Establishing a setup password through Computer Setup prevents reconfiguration of the computer (use of the Computer Setup (F10) utility) until the password is entered. 5. Put the jumper back on pins 4 and 6. 6. Replace the chassis access panel and reconnect the power cord. 7. Turn on the computer and allow it to start. Establishing a Setup or Power-On password 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. To establish a Setup password, select Security > Setup Password and follow the instructions on the screen. - or To establish a Power-On password, select Security > Power-On Password and follow the instructions on the screen 4. Before exiting, click File > Save Changes and Exit. Changing a Setup or Power-On password If the system is equipped with an embedded security device, refer to the HP ProtectTools Security Manager Guide at http://www.hp.com. 1. Turn on or restart the computer. If you are in Windows, click Start > Shut Down > Restart. To change the Setup password, go to step 2. To change the Power-on password, go to step 3. 2. 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. 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 If the system is equipped with an embedded security device, refer to the HP ProtectTools Security Manager Guide at http://www.hp.com. 1. Turn on or restart the computer. If you are in Windows, click Start > Shut Down > Restart. To delete the Setup password, go to step 2. To delete the Power-On password, go to step 3. 2. 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. When the key icon appears, type your current password followed by a slash (/) or alternate delimiter character as shown. Example: currentpassword/ 4. Press Enter. dx7500 Illustrated Parts & Service Map, MT chassis 506597-001 page 4
