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.
The BIOS was unable to
find a suitable boot

Recommended Action
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.
Shut down the system, reseat the DIMMs,
and reboot the system. If the problem
persists, contact the system dealer for a
replacement.
None.
Shut down the system, ensure that the
power and data cables of all storage
devices are plugged in properly, and
reboot the system. If the problem persists,
contact an authorized service center for
assistance.
