SYSTEM BIOS

The BIOS performs memory detection and configuration with the following steps:

1.Program the buffer strength control registers based on SPD data and the DIMM slots that are populated.

2.Determine the common CAS latency that can be supported by the DIMMs.

3.Determine the memory size for each DIMM and program the GMCH accordingly.

4.Enable refresh.

8.3.4Boot Error Codes

The BIOS provides visual and audible indications of a failed system boot by using the system’s power LED and the system board speaker. The error conditions are listed in the following table.
