during POST
CD-ROM/DVD-
ROM not
recognized by
BIOS/EFI
Cause(s)
VRM converters not plugged in
or bent pins.
Cables not fully seated.
Power cord(s) not plugged in.
Bent pin on board or VRM
converters.
Short on one of the boards due
to conductive item touching it.
No memory found due to board
not being fully inserted into
connector.
Boards, VRMs, or processors not
fully seated.
Wrong stepping of processor in
system for the BIOS.
Memory not installed in
documented order or
unsupported/validated DIMMS
used.
Processors not fully seated.
VRMs not added to support
processors 3 and 4.
Bent pin(s) on processor(s).
Processor, VRM converters, or
cables not fully seated.
Bad VRM converter.
Memory board or DIMM not
functional.
Drives not fully seated.
IDE cable or power cable not
connected to drives.
Solution(s)
Check seating of cables on all boards and
VRM converters.
Ensure the power cord(s) is plugged into the
wall and power supply.
Ensure green light indicating AC is detected
is on.
Check to make sure that a screw or other
conductive item has not been dropped into
the system.
Check the connections on all cables and
VRM converters. (Begin with those
connections that gave you the most trouble
during installation. That is typically where a
pin may have gotten bent.)
Ensure the memory boards and Intel®
Management Module are fully seated.
Check for bent pins on processors.
Check seating on all boards, VRM
converters, and processors.
Check the BIOS release notes to ensure the
BIOS installed on the platform supports the
stepping and family of the processors
currently installed.
Check that you have populated the memory
banks in the proper order. See system
documentation for proper installation order.
Use only validated DIMMS.
Check seating on processors and
VRMs.
Verify that no processor pins are bent.
Check seating on all cables, VRM
converters, and processors. Check for bent
pins on all connectors.
Replace VRMs.
Check seating of all memory boards and
DIMMs.
Replace DIMMs.
Ensure proper population of DIMM banks.
Reinsert hard drives.
Ensure SCSI cable is connected to the SCSI
backplane board and the main board.
Check seating of drive into adapter board.
Check that BIOS setup has this device
enabled.
