POST Error Message Description
BIOS ROM checksum error - System
halted 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
System BIOS on page 60 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:

CMOS battery failed The CMOS battery is no longer functional. For information on replacing the
battery, refer to
Removing and Replacing the Battery on page 15 .
CMOS checksum error - Defaults loaded 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
Removing and Replacing the Battery on page 15 .

Hard Disk Install Failure 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 .
Keyboard error or no keyboard present 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.
Memory Test This message displays during a full memory test, counting down the memory
areas being tested.
Memory Test Fail If POST detects an error during memory testing, additional information appears
giving specifics about the type and location of the memory error.
Override enabled - Defaults loaded 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 TAB to show POST screen Press the Tab key during POST to display messages hidden by the HP logo.
Error: Non-System disk or disk error 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. For more
information, refer to
Restoring the Flash Image on page 47 .
