BIOS says: Checksum error, defaults loaded. I use a removable SSD for ML, and a removable HDD for WIN7. The strange thing: Using WIN7 I dont't have the BIOS problem.

People have suggested loading the config defaults and redoing the necessary changes for the OS X installation. Have you upgraded the bios recently? It could be corruption of the flashed bios. You could try a bios upgrade. To tell you the truth, I could not solve the problem on the computer. The most annoying thing about the error is that it wipes my boot sequence preferences and I can only boot form DVD or SATA port 1. Let me know if you find a solution.

It seems that the new AppleRTC.kext v1.4 added functionatality is causing this Error.Initially, a workaround suggested by JUN Ho is to use the AppleRTC.kext from SnowLeopardThen by blocking a few jumps and calls in http://www.insanelymac.com/forum/topic/253992-cmos-resets-on-restarts-after-sleep-and-wake-in-107-lion/ the procedures of AppleRTC.kext, the Checksum Error was overcome. It appears APPLE has left in-situ much of their realtime testing code in this kext and these modifications do not apparently affect their basic functionatility in normal cases. On further investigation by tseug and with the assistance of his DumpCMOS.kext , an updated patch (post# 217) was prepared by blackosx. This patch for vanilla AppleRTC.kext is effective on the latest build 11A494a. (besides also on recent builds)This solution will not affect those osx86 setups which inherently have Sleep or Wake problems. However, it will overcome the CMOS Checksum Error caused by RTC register length of 0x04 or 0x08 in DSDT and eliminate log msg RTC: Only single RAM bank (128 bytes) if, when a RTC register length of 0x02 is used.Added 2nd day of July, 2011New patch for AppleRTC.kext of Lion GM - Build 11A511 by tseug (Post #248). The binary patch now, is a single unconditional jump for each arch to bypass Checksum changes.Added 10th day of July, 2011An alternate patch for AppleRTC.kext of Lion GM.

The CMOS contains data cmos checksum related to BIOS and may have been reinitialized. It may also be possible to fix the problem by reinitialising BIOS. The problem could also occur due to the depletion of the CMOS battery. If the user cannot locate the pin battery, the help of a computer technician should be taken to prevent damage to the hardware or motherboard. The cmos checksum error CMOS checksum error - defaults loaded should be solved after changing the CMOS battery. Symptoms Solutions: Symptoms When starting your PC, the following error message is displayed: CMOS wrong CMOS MEMORY size WRONG CMOS Checksum Bad CMOS checksum error defaults loaded Warning! CPU has been changed please re-enter cpu settings in the cmos setup and remember to save before quit! You are prompted to: Press F1 to resume Press F2 to load default values and continue This is due to the fact that the CMOS, which contains data related to the BIOS, has been reinitialized and that your PC has been reset to factory settings. Solutions: Reinitializing the BIOS Before making any costly maintenance try: reinitialized the BIOS. Change BIOS battery If the problem persists this may be due to the fact that the battery powering the CMOS (when the computer is shut down it allows the CMOS to store information), is depleted. The CMOS battery is a small pin found on the motherboard; you can refer to the manual provided with your
by Vahan If you experience CMOS checksum errors and CMOS resets on wake or reboot after installing OS X 10.8 Mountain Lion on your Hackintosh, you need to patch the AppleRTC.kext. Open your Terminal and follow these easy steps: 1. First backup the original kext: mkdir ~/Desktop/BackupRTC sudo cp -r /System/Library/Extensions/AppleRTC.kext ~/Desktop/BackupRTC/ 2. Copy the original kext to your desktop for patching: sudo cp -r /System/Library/Extensions/AppleRTC.kext ~/Desktop/ 3. Patch it: sudo perl -pi -e 's|\x75\x30\x89\xd8|\xeb\x30\x89\xd8|' ~/Desktop/AppleRTC.kext/Contents/MacOS/AppleRTC 4. Delete the original version: sudo rm -rf /System/Library/Extensions/AppleRTC.kext 5. Copy the patched version in the place using Kext Wizard, rebuild the permissions and the system cache. 6. Reboot.
