Losing the System’s Setup Confi guration
1. Make sure that you are using a high quality power supply. A poor quality power
supply may cause the system to lose the CMOS setup information. Refer to
Section 1-6 for details on recommended power supplies.
2. The battery on your motherboard may be old. Check to verify that it still supplies
~3VDC. If it does not, replace it with a new one.
3. If the above steps do not fi x the Setup Confi guration problem, contact your
vendor for repairs.
NOTE
If you are a system integrator, VAR or OEM, a POST diagnostics
card is recommended. For I/O port 80h codes, refer to App. B.
Memory Errors
1. Make sure the DIMM modules are properly and fully installed.
2. Determine if DIMMs of different speeds or types have been installed and verify
that the BIOS setup is confi gured for the fastest speed of RAM used. It is
recommended to use the same RAM speed for all DIMMs in the system.
3. Make sure you are using the correct type of DDR2 Fully Buffered (FBD) ECC
667/533 SDRAM (recommended by the manufacturer.)
4. Check for bad DIMM modules or slots by swapping a single module between
four slots and noting the results.
5. Make sure all memory modules are fully seated in their slots.
6. Check the position of the 115V/230V switch on the power supply.
