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 that the DIMM modules are properly and fully installed.
2. You should be using unbuffered DDR2 memory (see the next page). Also, it is
recommended that you use the same memory speed for all DIMMs in the
system. See Section 2-4 for memory limitations.
3. Check for bad DIMM modules or slots by swapping modules between slots and
noting the results.
4. Check the power supply voltage 115V/230V switch.
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.
