C–2
Probable Cause
The checksum of the BIOS
code in the BIOS chip is
incorrect, indicating that the
BIOS code may have become
corrupt.
The CMOS battery is no
longer functional.
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.

the CPU.
Cannot find or initialize the
hard drive controller or the
drive.
Cannot initialize the

361685-001
Recommended Action
Verify the correct ROM.
Flash the ROM is needed.
If an expansion card was recently added,
remove it and see if the problem remains.
Clear CMOS.
If the message disappears, there may be a
problem with the expansion card.
Replace the system board.
Replace the RTC battery.
Check the battery and replace, if necessary.
None.
The user may press ESC to skip the full memory
test.
Make sure the controller is installed correctly in
the BIOS. If no hard drives are installed, be
sure the Hard Drive selection in Setup is set to
NONE.
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.
None.
