supplies ~3VDC. If it does not, replace it with a new one.

3.If the above steps do not fix the Setup Configuration 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. Check if DIMMs of different speeds or types have been installed. Also make sure that the BIOS setup is configured for the fastest speed of RAM used.

2.It is recommended to use the same RAM speed for all DIMMs in the system. Make sure you are using the correct type of Single-Rank, Registered ECC DDR2 667/533 SDRAM (recommended by the manufacturer.)

3.Check for bad DIMM modules or slots by swapping a single module between four slots and noting the results. Make sure all memory modules are fully seated in their slots. As an interleaved memory scheme is used, you must install two modules at a time, beginning with DIMM 1A, then DIMM 2A, and so on (see Section 2-3). Check the position of the 115V/230V switch on the power supply.
