CMOS Clear Jumper (JBT1). Refer to chapter 2.
2. Remove all components from the motherboard, especially the DIMM modules.

bad DIMM modules or slots by following the Memory Errors Troubleshooting procedure
in this Chapter.

the same memory type and speed for all DIMMs in the system. See Section 2.4 for
memory details.
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.
