Hard disk CMOS mismatch

Explanation: Some systems will automatically examine the IDE hard disk(s) in the system and compare its/their geometry to the parameters entered for it in the BIOS settings. If the values do not match this message may be generated.

Diagnosis: The usual cause of this message is changing the hard disk drive and forgetting to change the hard disk settings in the BIOS setup program. Otherwise it could indicate a hard disk or controller problem.

Recommendation:

Double-check the hard disk BIOS settings and ensure that they are correct. Use autodetection to make sure the correct values are chosen.
Troubleshoot the hard disk drive.
Troubleshoot the hard disk controller.
