Thank you and sorry for my poor English Hi 1. Turn the p/c off and remove the power cable. 2. Press the power button to remove any static power from the capacitors. 3. Remove the CMOS Battery for approximately 2 minutes and then replace it. 4. Replace the CMOS Battery and power cable. 5. Turn the p/c on and boot directly into the BIOS and load Optimize/Default BIOS settings and save. 6. Reboot back into the BIOS and change the settings from Optimize/Default BIOS settings to the ones to enable OS X, when done save and reboot. Hopefully with the above steps your board will be back to operational use for both Windows and OS X. Good luck. Link to comment Share on other sites More sharing options...
