Description
A video error has occurred and the BIOS cannot initialize the video screen to display any additional
information.
System running in boot block recovery mode.
Description
The checksum of the BIOS code in the BIOS chip is incorrect, indicating the BIOS
code may have become corrupt. To restore a corrupt BIOS, refer to Appendix D,
"System BIOS" or call your local HP Call Center for a diagnosis. For phone
numbers of an HP Call Center near you, visit the following Web site:

The CMOS battery is no longer functional. For information on replacing the battery,
refer to Appendix E, "Replacing the CMOS Battery."
Checksum of CMOS is incorrect, so the system loads the default equipment
configuration. A checksum error may indicate that CMOS has become corrupt. A
weak battery may have caused this error. Replace the battery if necessary. For
more information, refer to Appendix E, "Replacing the CMOS Battery."

Cannot find or initialize the hard drive controller or the drive. Make sure the
controller is installed correctly. If no hard drives are installed, be sure the Hard
Drive selection in Setup is set to NONE.
Cannot initialize the keyboard. Make sure the keyboard is attached correctly and
no keys are pressed during POST. To purposely configure the system without a
keyboard, set the error halt condition in Setup to HALT ON ALL, BUT
KEYBOARD. The BIOS then ignores the missing keyboard during POST
This message displays during a full memory test, counting down the memory areas
being tested.
If POST detects an error during memory testing, additional information appears
giving specifics about the type and location of the memory error
If the system cannot boot using the current CMOS configuration, the BIOS can
override the current configuration with a set of BIOS defaults designed for the most
stable, minimal-performance system operations.
Press the TAB key during POST to display messages hidden by the HP logo.
The BIOS was unable to find a suitable boot device. For the t5000 Series, this may
mean an uninitialized or corrupt ATA Flash. Reflash the unit and press any key
when ready. For more information, refer to Chapter 5, "Restoring the Flash Image."
